Answer:

Step-by-step explanation:

a^{m}*a^{n}=a^{m+n}\\\\\frac{a^{m}}{a^{n}}=a^{m-n}\\\\(a^{m})^{n}=a^{m*n}\\\\a) 3^{5}*3^{x} = 3^{3}*9=3^{3}*3^{2}\\\\ 3^{5+x} =3^{3+2}

Compare the exponents,

5 +x = 5

     x = 5-5

      x = 0

b) \frac{4^{x}*4^{8}}{4^{2}}=(4^{7})^{1}\\\\4^{x+8-2}=4^{7*1}\\4^{x + 6}=4^{7}

Compare the exponents,

x +6 = 7

    x = 7-6

    x = 1

c)\frac{a^{8}*a^{5}}{a^{2}}=\frac{a^{x}}{a^{2}}\\\\a^{8+5-2}=a^{x-2}\\\\a^{11}=a^{x-2}

Compare the exponents,

x - 2 = 11

     x = 11+2

    x = 13

d)\frac{(5^{3})^{x}}{5^{6}}=5^{10}*5^{8}\\\\5^{3x-6}=5^{10+8}\\\\5^{3x-6}=5^{18}

Compare the exponents,

3x -6= 18

3x = 18 + 6

3x = 24

  x = 24/3

x = 8

Given the following rectangle and circle, at what approximate value of x are the two areas equal? Show work and explain all step
suter [353]

Answer:

x ≈ 1.28

Step-by-step explanation:

I just took the exam:

Area of rectangle =(3x-1)(x+6), Area of circle = PI(x+1)^2. If you graph these and find where they intersect, you will get x ≈ 1.28.

I hope this helped! :)

I need help on this math question?​
oksian1 [2.3K]

Answer: C

Step-by-step explanation:

from the expression, (⁵/₈)⁻²

Recall from the laws of indicies,

a⁻¹ = ¹/a , it is called reciprocal law in indicies.

Therefore,

(⁵/₈)⁻² = ¹/(⁵/₈)²

        = ¹(²⁵/₆₄)

Therefore, to resolve this, it will be

      1 ÷ ²⁵/₆₄

        = 1 ˣ ⁶⁴/₂₅

        = ⁶⁴/₂₅

The answer is ⁶⁴/₂₅ which is C in the provided options.
