We will learn how to convert between radicals and rational exponents in this lesson. Therefore, it is a good idea to brush up on your understanding of all the basic rules of exponents before stating to watch the lesson.

Basic Concepts: Evaluating and simplifying radicals, Converting radicals to mixed radicals, Converting radicals to entire radicals, Combining the exponent rules

Related Concepts: Conversion between entire radicals and mixed radicals, Exponents: Rational exponents

${A^{x/y}} = {^y}\sqrt{A^x}$

- Introductiona)How to convert between radicals and rational exponents?
- 1.Write the following in the radical forma)${27^{- \frac{2}{3}}}$b)$(-8 {)^{- \frac{3}{5}}}$
- 2.Write the answer with positive exponents and then as entire radicala)$( \frac{9}{4}{)^{- \frac{3}{4}}}$b)$-(-16 {)^{- \frac{4}{5}}}$c)$\frac{(5 {x^\frac{3}{7}} )}{(25 {x^{- \frac{3}{7}})}}$
- 3.Write the answer as a power and evaluatea)${^5}\sqrt{a^3}$b)$1/ {^4}\sqrt{a^7}$c)$\sqrt{{^3}\sqrt{81}}$d)$(4 {^3}\sqrt{y} )(3 {^3}\sqrt{y} )$e)$( {^4}\sqrt{3y-4} {)^{-3}}$f)$- {^5}\sqrt{(-x{)^3}}$
