Question 1190689
<font color=black size=3>
Any nonzero number to the exponent of 0 will result in 1.
{{{z^0 = 1}}} as long as {{{z <> 0}}}
Multiplying by 1 has no effect, so the z^0 won't affect the answer.


The {{{z^(-10)}}} portion then turns into {{{1/(z^(10))}}} when we make the exponent positive. Take the reciprocal of the base to make the exponent positive. 
The general rule is that {{{a^(-b) = 1/(a^b)}}} or you can think of it like {{{(a/b)^(-c) = (b/a)^c}}}


Answer: {{{1/(z^(10))}}}
