When you take the square root of a positive integer, how many possible answers are there? when you take the cube root of a positive or negative integer, how many possible answers are there?

When you take the square root of a plus number, you get 2. It is often written as +/- something. 
For example sqrt 64 = +8 and - 8 

(8)*(8) = 64
(-8)(-8) = 64 Remember when 2 minus' are multiplied together, you get a plus.

Oddly, when you take the cube root of something, you get only 1 answer. When you take an advanced math course, you will find out that it is three. But until you know what a complex number is, the answer is 1.
