Chapter 7.2(c) Rational Exponents

Use rational exponents to simplify radical expressions

Mar 21­7:58 AM

Some radical expressions are easier to simplify if we write them with rational exponents and then simplify.

Rational Exponents to Simplify Radical Expressions

Start with writing the expression with rational exponents

Use exponent properties to simplify

Convert back to radical notation.

Example:
