This lessons starts to get into some higher order roots. Cube roots and fourth roots (and even higher) are shown and explained in this lesson. The concept of changing the index in front of the radical sign and computing answers or simplifying expressions is explained step by step. Also, higher roots of numbers and variable expressions are broken down and simplified. This is a great transition into higher order roots of expressions.
