Answer:
The expression is 1/16 when x = -2, The expression is 64 when x = 3.
Step-by-step explanation:
Part A)
Evaluate 4^x for x = -2. Write your answers in simplest form:
= 4^(-2)
= 1/4^2 ( 1 / 4 * 4)
= 1/16
Part B)
Evaluate 4^x for x = 3. Write your answers in simplest form:
=4 ^ 3
= 4 * 4 * 4
= 16 * 4
= 64
