Simplify radicals.

A radical is "simplified" when the radicand has no perfect-power factors (matching the index), and there are no fractions inside or radicals in a denominator.
| Radicand | →the expression UNDER the radical |
| Index | →the small number ON the radical (2 = square root, 3 = cube root) |
| Index 2 (the default) | →look for perfect-square factors: 4, 9, 16, 25, … |
| Index 3 | →look for perfect-cube factors: 8, 27, 64, 125, … |
