Question

Evaluate the following without a calculator:
1. (25/4)^(3/2)
2. (4(3)^-2)/(2^-2)(3^-1)

Answer 1

start by writing 25 and 4 in exponent form. ex. 36 = 6^2

Answer 2

so would that be 125 over 8?

Answer 3

yes

Answer 4

cool thanks :D, although im still unsure about the other problem

Answer 5

simply evaluate each exponent as you come to it.
\[(4*3^{-2})/[(2^{-2})*(3^{-1})]\]
is this what the original expression is.
