WebTo find the square root of a number x x, we look for a number whose square is x x. For example, since 3^2=9 32 = 9, we say that the square root of 9 9, written as \sqrt 9 9, is 3 3. 3^2=9 \iff 3=\sqrt 9 32 = 9 3 = 9. Similarly, to find the cube root of a number x x, we look … Web( 3 votes) David Severin 6 years ago FIrst off, we cannot have a negative on any of our even roots (square, 4th, 6th, etc.) without getting into imaginary numbers. So if you are asking (-.5)^ (1/5) we could write the square root sign with a raised 5 on the crook of the root sign, and a -.5 inside. Hope this helps. ( 5 votes) Icedlatte 6 years ago
