6-101.

Rewrite each expression below so that your answer contains no parentheses and no negative exponents.

1. $(-\frac { 2 } { 3 }x^5y^{1/3})^0$

Anything to the zero power equals $1$.

1. $(25^{1/2}x^5)(4x^{-6})$

When multiplying like bases, add their exponents.

$\frac{20}{x}$

1. $5t^{-3}$

The '$-3$' only applies to the $t$, not the $5$.

1. $( \frac { x ^ { 7 } y ^ { 3 } } { x } ) ^ { 1 / 3 }$

Start by simplifying the part of the expression inside of the parentheses.
