Question

simplify
mn^-4
-------
p^0q^-2

Answer 1

So by simplify I assume they want `no negative exponents in your result, yes?

Answer 2

\(\Large\rm \dfrac{m^{-4}}{p^0q^{-2}}\)

Start with the p first.
Do you emember what happens when you raise something to the 0 power?

Answer 3

\(\bf \cfrac{mn^{-4}}{p^0q^{-2}}\implies \cfrac{m}{1}\cdot \cfrac{1}{p^0}\cdot \cfrac{n^{-4}}{1}\cdot \cfrac{1}{q^{-2}}\implies ?

\textit{keep in mind that }a^{-{\color{red} n}} = \cfrac{1}{a^{\color{red} n}}\qquad \qquad

\cfrac{1}{a^{-\color{red} n}}\implies \cfrac{1}{\frac{1}{a^{\color{red} n}}}\implies \large a^{{\color{red} n}} \)
