7.3 rational exponents
- 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! рThe 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
