• simplify algebraic expressions including roots (and powers), including
• expressions in just one variable,
• expressions in many variables,
• understand how to utilize moduli to respect the domain of root expressions, where is even,
• solve algebraic equations that require the evaluation of an root.

#### Prerequisites

Students should already be familiar with

• rules of exponents,
• the concept that the root of is if is odd and and if is even.

#### Exclusions

Students will not cover

• expressing roots and powers as fractional exponents.
