When simplifying a value with a rational exponent, which part should you do first?

• Root
• Power

Write the following expression in radical form:

• a.)

• b.)

• c.)

• d.)

Answer explanation

Remember, power over root!

Simplify the following expression:

• 5
• 25
• 125
• 625

Simplify . Your answer should contain only positive exponents.  $\left(6b\right)^{\frac{-4}{3}}$  

•  $\frac{1}{6^{\frac{4}{3}}b^{\frac{4}{3}}}$  

•  $\frac{6}{b^{\frac{4}{3}}}$  

•  $\frac{b^{\frac{4}{3}}}{6}$  

•  $\frac{6^{\frac{4}{3}}}{b^{\frac{4}{3}}}$
