Question

Find all the real square roots of -9/16
A. No real root
B. -3/4
C. -3/4 and 3/4
D. 81/256

Answer 1

You can simply tell that the square root of 9 would be 3 (3*3=9) and the square root of 16 would be 4 (4*4=16), however you can not have a negative or positive number for the square root of a negative number. The square root of -9 would be 3i -- which is Imaginary 3.

From this information, what does the correct answer choice seem to be?
