Aplicando las leyes de los exponentes de potencia, los resultados son los siguientes:

En este ejercicio debemos aplicar cualesquiera de las siguientes propiedades asociadas a los exponentes:

(i) [tex](a^{b})^{c} = a^{b\cdot c}[/tex]

(ii) [tex]a^{c}\cdot b^{c} = (a\cdot b)^{c}[/tex]

(iii) [tex]a^{-b} = \frac{1}{a^{b}}[/tex]

(iv) [tex]a^{b} = a^{b}[/tex], donde [tex]a[/tex] es negativo o positivo y [tex]b[/tex] es par.

(v) [tex](-a)^{b} = -a^{b}[/tex], donde [tex]a[/tex] es positivo y [tex]b[/tex] es impar.

(vi) [tex]a^{b}\cdot a^{c} = a^{b+c}[/tex]

A continuación, tenemos los siguientes resultados:

a) [tex](2^{3})^{7} = 8^{7} = 2097152[/tex]

b) [tex](3^{3})^{-2} = 3^{-6} = \frac{1}{729}[/tex]

c) [tex](b^{3})^{4}=b^{12}[/tex]

d) [tex][(x^{2})^{3}]^{4} = (x^{6})^{4} = x^{24}[/tex]

e) [tex]\left(x^{\frac{3}{5} }\right)^{2} = x^{\frac{6}{5} }[/tex]

f) [tex](3\cdot 4\cdot 2)^{5} = 3^{2}\cdot 4^{2}\cdot 5^{2} = 9\cdot 16\cdot 25 = 3600[/tex]

g) [tex](a^{3}\cdot b^{5}\cdot c^{-4})^{2} = (a^{3})^{2}\cdot (b^{5})^{2}\cdot (c^{-4})^{2} = a^{6}\cdot b^{10}\cdot c^{-8}[/tex]

h) [tex](2\cdot x^{5})^{3}\cdot (-5\cdot x^{2})^{2} = (2^{3}\cdot x^{15})\cdot [(-5)^{2}\cdot x^{4}] = (8\cdot x^{15})\cdot (25\cdot x^{4}) = (8\cdot 25)\cdot x^{19} = 200\cdot x^{19}[/tex]

i) [tex]\left(3\cdot y^{\frac{2}{3} }\right)^{3}\cdot (2\cdot y^{2})^{2} = (27\cdot y^{2})\cdot (4\cdot y^{4}) = 108\cdot y^{6}[/tex]

Answer:

x=-8

Step-by-step explanation:

An undefined slope is a vertical line, and the equation for one is always x=(Whatever number x is at those points).

Therefore, with our point of (-8, 2), the equation must be x=-8

Answer:

12.75

Step-by-step explanation:

12.75 rounded to the nearest tenth is 12.8, and 12.74 won't work because it will round to 12.7.

Therefore, 12.75 is the smallest possible number.

adult ticket = 10

child ticket = 4

Step-by-step explanation:

for example…

so that we get a system of equations

9x + 5y = 110…Equation 1

x + y = 14…Equation 2

solve the system of equations, this time I will use the Elimination and Substitution method

9x + 5y = 110

x + y = 14 (multiplied by 5)

↓↓↓↓↓↓↓

9x + 5y = 110

5x + 5y = 70

___________ _

4x = 40

x = 10

to find value of y subtitute x to one of Equation. for example from second Equation…

x + y = 14

10 + y = 14

y = 14 - 10

y = 4

∴ So, the number of each ticket was she bought is 10 adult ticket and 4 child ticket.

Answer:

A. Perpendicular

Answer:

D

Step-by-step explanation:

The range is all of the y values that make a function true. Our graph here starts at y=-2 and then goes up for infinity. This means the range is y ≥ -2. The domain is [0, ∞) because our x values start at 0 and go to infinity. This means the domain is restricted so A is not true, B is not true because the graph does not exist at x = -2.

Answer: x = 7

Step-by-step explanation:

Subtract both sides by 3

X+3-3 = -4 - 3

X+0 = -7

X=-7

Answer:

-7

Step-by-step explanation:

x+3=-4

x=-4-3 (subtract 3 from both sides)

x=-7 (combine like terms)

Answer:

{(0, -4), (1, -2), (2, 0), (3, 2), (4, 4)}

Input values (x) = {0, 1, 2, 3, 4}

Output values (y) = {-4, -2, 0, 2, 4}

Step-by-step explanation:

Given the linear equation, y = 2x - 4, you could practically choose any input value (for x), to have an output value (for y).

If x = 0:

y = 2(0) - 4

y = 0 - 4

y = -4

First ordered pair: y-intercept =  (0, -4)

If x = 1:

y = 2(1) - 4

y= 2 - 4

y = -2

Second ordered pair: (1, -2).

If x = 2:

y = 2(2) - 4

y= 4 - 4

y = 0

Third ordered pair: x-intercept =  (2, 0).

If x = 3:

y = 2(3) - 4

y = 6 - 4

y = 2

Fourth ordered pair: (3, 2).

If x = 4:

y = 2(4) - 4

y = 8 - 4

y = 4

Fifth ordered pair: (4, 4).

Your input values (x) = {0, 1, 2, 3, 4}

Your output values (y) = {-4, -2, 0, 2, 4}

Answer:

I got x = 20

Step-by-step explanation:

what i did was 8x - 25 = 7x -5, i then did  8x - 25 + 5 = 7x -5 +5 then you get 8x - 20 = 7x  I then did 8x - 20 -8 = 7x -8 you would get -20 = -1x or -x and -20/-1 = x = 20 I hope this works : )

Answer: empty set

Step-by-step explanation:

All prime numbers only have two factors.

[tex]growth\:=(\frac{present \: value}{past \: value})^{ \frac{1}{n} } \: - 1 [/tex]

past value = 1700 people

n = 2005 - 1983 = 22

growth rate = 190%

present value = ?

then,

[tex]190\% = ( \frac{?}{1700})^{ \frac{1}{22} } - 1[/tex]

1.9 = (x/1700) ^(1/22) - 1

1.9 + 1 = (x/1700) ^(1/22)

2.9 = (x/1700) ^(1/22)

log 2.9 = 1/22(logx - log 1700)

log2.9 = 1/22logx - 1/22log1700

log2.9 + 1/22log1700 = 1/22logx

log(2.9 * 1/22(1700)) = 1/22logx

log 224 = 1/22logx

log(224 - 1/22(x)) = 1

log(224 - 1/22(x)) = log 10

224 - 1/22(x) = 10

(234) * 22 = x

x = 5148.

Answer:

f(3) = 100

Step-by-step explanation:

Using the recursive formula and f(1) = 1 , then

f(2) = - 10 f(1) = - 10 × 1 = - 10

f(3) = - 10 f(2) = - 10 × - 10 = 100

if 9m away from deep point, m1 also away from 9m to radius line.

so if we draw 2 x 2y to 1 half side of circle, y is connected with 9m, x is connected to 6m.

2 x = 150 sec

if i say 1 x 6m 2x 12m

x =75 sec =12.5 sec

(2x +2y ).2 is whole circle round
