1. 7-5 Rational Exponents
Fraction Exponents

2. Radical expression and Exponents
By definition of Radical Expression. The index of the Radical is 3. The index of the Radical is 2.

3. If you don’t see the index number, then the index is 2.
If you don’t see the index number, then the index is 2.

4. How would we simplify this expression?
What does the fraction exponent do to the number? The number can be written as a Radical expression, with an index of the denominator.

5. The Rule for Rational Exponents

6. Write in Radical form

7. Write each Radical using Rational Exponents

8. For any nonzero real number b, and integer m and n
Make sure the Radical express is real, no b<0 when n is even.

9. What if the numerator is not 1
Evaluate

10. Simplify
