(1/2) to the -2 power

1 answer

To evaluate the expression (1/2)^-2, we need to follow the rules of exponents.

The negative exponent flips the fraction and makes it positive. Thus, (1/2)^-2 becomes (2/1)^2.

(2/1)^2 is equal to 2^2/1^2, which is 4/1 or simply 4.

Therefore, the expression (1/2)^-2 is positive.
