Rational Exponents When a base is raised to a rational exponent of the form 1/n we use the following definition: The denominator of the rational exponent.

Note that the denominator of the exponent becomes the index and the base becomes the radicand. Example Write an equivalent expression using radical.

5.7 Rational Exponents 1 Rules 2 Examples 3 Practice Problems

Rules All previous rules concerning exponents apply Converting From Radical Form to Rational Exponent Form A radical number may be represented as a number taken to a fractional exponent Steps Write the radicand Write a fractional exponent The index number is the denominator The power of the radicand is the numerator

Example Write the radical as a rational exponent Note: Reverse the process to express a rational exponent as a radical

More Examples Express as a radical Express as a rational exponent
