Question

Help needed :/
(1/2^-2) + 1/2
A. 2
B. 2 1/2
C. 4
D. 4 1/2

Answer 1

`(1)/(2)^(-2)` When you have a fraction to a negative power, you flip the number over, and then act like it's to the positive power. So this equals.
`(2)/(1)^2`. Now you simply have to evaluate
`2^2`, which is 4.

C. 4 (not to be confused with the explosive... :P)
