Question 76898
<pre><font size = 4><b>
Hi I dont really understand what to do here. 
(-5) to the 0 power multiplied by X to the -1 power

(-5)<sup>0</sup>x<sup>-1</sup>

Any number to the zero power is 1, so write (1) in place of
(-5)<sup>0</sup>.

Now you have

(1)x<sup>-1</sup>

Now use the rule that the -N power of any number is the
reciprocal of the number to the N power. So write 
{{{1/x}}} in place of x<sup>-1</sup>

{{{(1)(1/x)}}}

or just

{{{1/x}}}
