Use various rules for exponents to simplify this expression. See explanation below.

The first rule for exponents will will utilize is:

$(x^color(red)(a))^color(blue)(b) = x^(color(red)(a) xx color(blue)(b))$

This simplifies our expression to:

$q^(color(red)(1/5) xx color(blue)(5)) xx q^(color(red)(2/3) xx color(blue)(3)) =$

$q^(color(red)(1)) xx q^(color(red)(2)$

The next rule of exponents we can use is:

$x^color(red)(a) xx x^color(blue)(b) = x^(color(red)(a) + color(blue)(b))$

Using this rule allows us to simplify our expression to:

$q^(color(red)(1)+color(red)(2)) =$

$q^3$
