-8cot square A + 8 cosec square A​

Answers

Answer 1

Answer:

8

Step-by-step explanation:

Using the identity

cosec²A = 1 + cot²A

- 8cot²A + 8cosec²A

= - 8cot²A + 8(1 + cot²A)

= - 8cot²A + 8 + 8cot²A

= 8

Answers

Answer:

w = 242

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

[tex]11=-w + 253[/tex] [tex]-w + 253 = 11[/tex]

Step 2: Subtract 253 from both sides.

[tex]-w + 253 - 253 = 11 - 253[/tex] [tex]-w = -242[/tex]

Step 3: Divide both sides by -1.

[tex]\frac{-w}{-1}=\frac{-242}{-1}[/tex] [tex]w = 242[/tex]

Step 4: Check if solution is correct.

[tex]11 = 253 - (242)[/tex] [tex]11 = 253 - 242[/tex] [tex]11 = 11[/tex]

Therefore, w = 242.

The simplest form of  6⁵ x 6² is 6⁷    

Exponents:

The way of representing huge numbers in terms of powers is known as an exponent. The exponent of a number is the number of times a number has been multiplied by itself.  

For example, 3 is multiplied by 4 times itself, i.e. 3 × 3 × 3 × 3. This can be represented as 3⁴. Where 3 is the base and 4 is the exponent.

The following are the some of formulas in exponents

=> aᵇ. aˣ = aᵇ⁺ˣ=> (ab)ˣ = aˣ bˣ=> (a/b)ˣ = aˣ/bˣ

Here we have

The expression 6⁵ x 6²  

We can simplify the given equation by using exponent formulas

As we know, aᵇ × aˣ = aᵇ⁺ˣ

=> 6⁵ x 6² = 6⁵⁺² = 6⁷    

Therefore,
