Evaluate the expression:
(2^-2)^-2
A. 1/16
B. 2
C. 8
D.16
A. 1/16
To solve this expression, we first evaluate the exponent inside the parentheses:
(2^-2)^-2 = (1/(2^2))^-2
= (1/4)^-2
= 1/(4^-2)
= 1/(1/16)
= 1 * 16
= 16
Therefore, the expression (2^-2)^-2 evaluates to 1/16. So, option A is the correct answer.
