Use the rules of exponents to evaluate or simplify. write without negative exponents. (1/4)^-1/2

±2

Step-by-step explanation:

(1/4)^-1/2

The negative exponent means it goes  in the bottom

1

(1/4) ^ 1/2

The square root of 1/4  = 1/2 * 1/2 = 1/4

                                           -1/2 * -1/2 = 1/4

1                    1

 or

1/2                   -1/2

We know 1 / (1/2) = 2

2   or -2

two data sets with the same median will not have the same varaibility
