Question:

Geoffrey is evaluating the expression (-3)^3(2^6)/(-3)^5(2^2) as shown below.

(-3)^3(2^6)/(-3)^5(2^2) = (2)^a/(-3)^b = c/d

What are the values of a, b, c, and d?

Answer:

The values are a = 4, b = 2, c = 16, d = 9

Solution:

Given that,

Geoffrey is evaluating the expression


((-3)^3 * 2^6)/((-3)^5 * 2^2)

He is evaluating as shown below:


((-3)^3 * 2^6)/((-3)^5 * 2^2) = (2^a)/(-3^b) = (c)/(d)

From given,


((-3)^3 * 2^6)/((-3)^5 * 2^2)

Use the law of exponent


(a^m)/(a^n) = a^(m - n)

Therefore,


((-3)^3 * 2^6)/((-3)^5 * 2^2) = (2^(6-2))/((-3)^(5-3))\\\\Simplify\\\\((-3)^3 * 2^6)/((-3)^5 * 2^2) = (2^4)/(-3^2)

Thus,

a = 4

b = 2

Simplify further


((-3)^3 * 2^6)/((-3)^5 * 2^2) = (2^4)/(-3^2) = (16)/(9)

Thus,

c = 16

d = 9

Thus values are a = 4, b = 2, c = 16, d = 9
