1. kropot72

The imaginary number i = square root of -1. Extracting -1 from under the radical sign gives: $\sqrt{-16}=i \sqrt{16}=?$

But can you find the square root of it?

3. MATHLOSER

The square root of 16 s 4 because 4*4=16

@FastLearner1234 The square root of the expression in your question can be found only by expressing the solution as an imaginary number.
