First of all √x = x^1/2 because it cancels out the equation x^2.
If you square a number and you want the original number you square, you take the square root.
Also x=x^1. and 1 can be written as 1/1 and 2/2 so in this case, when you multiply two similar variables with similar exponents you add them together, so 1/2 + 2/2 = 3/2
