Question

How do you find the square roots of the fraction -9/16

Answer 1

Real roots or complex number?

Answer 2

sqrt(-9/16)?

You're going to end up with a complex number.

sqrt(-9/16) = sqrt(9/16) * sqrt(-1)
sqrt(9/16) = sqrt(9)/sqrt(16) = 3/4

therefore sqrt(-9/16) = (3/4)i

Ah yes, I assumed it was a positive root.
