Rewrite each of the following expressions so that your answer has no negative or fractional exponents.

1. $16^{5/4}$

   Step 1(a):

   Rewrite the expression:

   $(16^{\frac{1}{4}})^5=(\sqrt[4]{16})^5$

   Step 2(a):

   First find the fourth root of 16.

   $\sqrt[4]{16}=2$

   Step 3(a):

   Now raise the 2 to the 5^th power.

   2⁵ = 32

   Answer (a):

   32

2. (x⁵y⁴ )^1/2

   Hint (b):

   $\text{Remember that a number raised to the }\frac{1}{2}\text{ power}$

   $\text{is the square root of that number.}$

   Answer (b):

   $\textit{x}^{2}\textit{y}^{2}\sqrt{\textit{x}}$

3. (x²y⁻¹)(x⁻³y)⁰

   Hint (c):

   Remember that any number to the 0 power is 1. Remember to rewrite it without negative exponents.

   $\left(x^{2}y^{−1}\right)\left(1\right)$
