## Fractional Exponents

Summary

The lesson delves into the concept of fractional exponents, elucidating their relationship with roots and offering strategic insights for simplifying expressions involving such exponents.

- Fractional exponents represent roots, with an exponent of 1/2 signifying a square root, 1/3 a cube root, and so forth.
- The lesson demonstrates how to solve for a variable when given an expression with a fractional exponent, using the example of 2 to the power of one-half.
- It introduces a method for dealing with fractional exponents that have numerators other than one, illustrating how to simplify expressions by either taking the root before raising to a power or vice versa.
- A practice problem is provided to apply the concept of choosing the most efficient method for simplification, emphasizing the strategy of making numbers smaller before making them bigger.
- The rules discussed apply to positive numbers and, with certain conditions, to negative numbers as well.
