8-55.

Simplify each expression.

1. $6^5$

$6 · 6 · 6 · 6 · 6$

2. $( \frac { 2 } { 3 } ) ^ { 3 }$

$\frac{2}{3}\cdot\frac{2}{3}\cdot\frac{2}{3}$

3. $\left(2 + 3\right)^{4}$

Following the Order of Operations, first simplify the terms in parentheses.

$\left(5\right)^{4}$

Then simplify the terms with exponents.

$5 · 5 · 5 · 5$

$625$

4. $2 ( - \frac { 1 } { 2 } + \frac { 3 } { 4 } ) ^ { 3 }$

$\frac{1}{32}$
