Express In simplified exponential notation.
18a^3b^2/ 2ab

Answers

Answer:

18a^3b^2/2ab

To simplify the given expression, we apply property of exponents

18/2 = 9

x^m / x^n= x^ (m-n) In division we subtract the exponents

So given expression becomes

9a^2b

The answer has only positive exponents

i think this is what you want?

The simplified exponential notation of the given expression is [tex]9a^2b[/tex].

The given expression is: [tex]\frac{18a^3b^2}{2ab}[/tex]

What is an exponential expression?

An expression in the form of [tex]a^pb^qc^r[/tex].. is called exponential expression.

We can write the above expression as:

[tex](\frac{18}{2} )(\frac{a^{3} }{a} )(\frac{b^{2} }{b} )[/tex]

We know that [tex]\frac{a^m}{a^n} =a^{m-n}[/tex]

[tex]\frac{a^{3} }{a} =a^{3-1} =a^{2} \\\frac{b^{2} }{b}=b^{2-1} =b[/tex]

So, [tex](\frac{18}{2} )(\frac{a^{3} }{a} )(\frac{b^{2} }{b} )[/tex] =[tex]9a^2b[/tex]

Hence, the simplified exponential notation of the given expression is [tex]9a^2b[/tex].

giving brainliest !!!

Answers

Answer:

156.6 meters squared

Step-by-step explanation:

There are 3 triangles for the sides. The area for a triangle is one half base times height. So we are doing one half of 9 times 9. This is 40.5. Since there are 3 of them we can just multiply 40.5 times 3 to get 121.5. And now to solve for the base triangle, it is one half of 9 times 7.8. We get 35.1. Now add together 121.5 and 35.1. We get 156.6. Now since this is surface area it is meters squared.

Sarah began the business this year, and while she has a great deal of experience in manufacturing popular and comfortable shoes, she needs some help in evaluating her results for the year, and asks for your help.Sarahs first questions for you have to do with the general ideas and terminology used to evaluate variances.1. Why might Sarah want to use standard costs to compare with her actual costs?a. Management can evaluate the differences between standard costs and actual costs to focus on correcting the cost variances.b. Standard costs give management a cost structure for products that is applicable for the entire life of the business.c. Standard costs allow management to motivate employees by comparing their performance to what it would be under perfect conditions.2. What are some possible drawbacks to using standard costs that Sarah might consider? Check all that apply.a. Since standards are impossible to attain, they are a distraction from the work at hand.b. Since standards never change, they do not reflect reality.c. Standards limit operating improvements because employees may be discouraged from improving beyond the standards.d. Employees may focus only on efficiency improvement and their own operations rather than considering the larger objectives of the organization.e. Standards may become "stale" in a dynamic manufacturing environment. Someone read this and just tell me in short words about what is says.Art can be made out of anything, including ordinary things we find around us.Everyday objects that we usually throw away, such as metal cans or bits ofnewspaper, can be reused to make sculpture, jewelry, or musical instruments, forexample. Their value depends on the artists ability to see how their shape, color,material, or design can be used in a new way. Some artists even recycle images andmaterials from other peoples art, adding personal touches or altering the originalartwork to make their own statement.A patchwork quilt is sewn together from scraps, remnants, and rags. Quilters,often working together, combine these irregular bits and pieces of cloth into a newpattern. In rural America, the traditional quilting bee gave friends and neighbors achance to get together and exchange news and gossip.Public places can become art spaces. Artists on New Yorks Lower East Sidehave transformed an old gas station into a gallery, sculpture garden, and performancespace. They turn abandoned cars and other urban debris into a community work ofart that continues to grow. . . .The German artist Kurt Schwitters (18871948) used discarded objects to createa style of art he called Rubbish. Schwitters walked the streets collecting torn piecesof paper, ticket stubs, and bits of stringanything someone had thrown awayandused glue to combine them on a plain background. That kind of picture is called acollage, from the French word for paste. . . .With a little imagination, any object can be used for art. During World War II, rawmaterials of all kinds were in short supply. The famous Spanish artist Pablo Picasso(18811973) hoarded junk such as bicycle frames, mattress springs, and gardeningtools, which he made into sculptures. Bulls Head, created in 1942, is made from abicycle seat and handlebars cast in bronze.Musical instruments can be made from recyclables. American composer HarryPartch (19011974) turned large glass bottles called carboys into an enormous setof hanging gongs. Partch named his instrument the Cloud-Chamber Bowls in 1950,when he found the tops and bottoms of carboys that had been cut in a laboratory . . . .Doing some experimenting of his own, he discovered ways of striking the bowls toproduce beautiful and complex tones.Have you ever stacked stones in a huge pile or built a fort out of sticks? Thenyoure an Earth Artist. You dont need paint or paper to make art: in fact, Earth ArtistAndy Goldsworthy started out with a simple rule: he would work outside and only usematerials he could find nearby. That meant using thorns to pin dried stalks togetherand spit to paste leaves to rocks! I splashed in water, covered myself in mud, wentbarefoot, and woke with the dawn, Goldsworthy says in the book Hand to Earth. Healso got rained and snowed on a lot, sometimes on purpose! To make a rain shadow,Goldsworthy lies down on the ground when its just beginning to rain, then gets uponce hes soaked and takes a picture of the man-shaped dry spot he left behind.Home is in Scotland, but Goldsworthy has worked in the United States, France,Australia, Japan, and even at the North Pole. His finished works made of stones,sticks, leaves, ice, sand, or mud look astoundingly simple and beautiful, but theprocess can be filthy and even frustrating. The purpose isnt just to make a nice pieceof artits a way of learning about the world. In his book A Collaboration with Nature,Goldsworthy says, I stop at a place or pick up a material because I feel there issomething to be discovered. Here is where I can learn.Gluing IciclesA man with white hair, a white beard, and a Scottish accent rubs his freezinghands together before picking up a piece of icicle, dipping it in snow and then inwater, and holding it against another bit of ice. Then he waits patiently until the twopieces freeze together.Andy Goldsworthy is being filmed in action for the documentary Rivers and Tides.The curving line of ice hes working on looks as if it weaves through and around apoint of stone. If a piece of icicle doesnt fit quite right, he chews the end until it does.His hands are cold and dirty, but he cant feel the ice properly with gloves on. Itshard going and its hard on the hands. . . . All effort is going into trying to makesomething that is effortless, he says.Finally, the Sun rises and shines through the curving ice; it seems to glow. I neverhad any idea that would happen! Goldsworthy says with delight, going on to pointout that the very thing that brings the work to life is the thing that will cause itsdeath. The ice will melt in the sunlight, and the sculpture will be gone.Balancing Stones True or False: The 425 Navajo Marines were part of an elite corps that were considered so valuable that they traveled with their own personal bodyguard. 1.
