Precalculus 11 – fraction exponents

This week, I learned how to solve numbers with fraction exponents. For example, 3^{\frac{1}{2}}. you write down the base, which is 3, then make a square root so the 2 in the exponent becomes the index and the 1 stays as the exponent. At the end, it would be \sqrt{3} (the index is 2 but it is invisible and 3^1 = 3 so no need to write down the 1.)
