8-32.

Change each expression into radical form and then give the value. No calculators should be necessary.

1.  $125^{2/3}$

Radical form should look like this:

$\sqrt[3]{125^2}$

1.  $16^{1/2}$

Radical form should look like this:

$\sqrt[2]{16^1}$

1.  $16^{−1/2}$

Use the same method seen in parts (a) and (b).

$\frac{1}{4}$

1.  $( \frac { 1 } { 81 } ) ^ { 1 / 4 }$

Use the same method seen in parts (a) and (b).

$\frac{1}{3}$
