.

2.  nth roots can be written using
rational exponents.
 For example:
 In general, for any
integer n greater than 1.

5.  Not always of the form 1/n.


 The denominator of the exponent is
the index of the radical!
“The bottom goes in the crack!”

7.  Write in radical form:

9.  Write in exponential form:

10.  Rewrite in radical form first.
 Evaluate the radical.
 Raise to the power.
 Example:
 93/2

11.  Evaluate.
 32-2/5
 642/3

12.  Evaluate:
 493/2
 16-3/4

13.  Rewrite in radical form first.
 Simplify the radical part.
 Raise everything to the power.
 Example:
 (36x4)3/2

14.  Evaluate.
 (a8)-3/4
 (216b9)5/3

15.  Evaluate:
 (9x4)-5/2
 (16y4)3/4
