    Refer to your rules for exponents 2m^2n^-1 or 2m^2/n

    \[2m ^{2}n ^{-1}\] or (sometimes preferred)\[2m ^{2}/n\]

    \[\frac{8m^3n^2}{4mn^3} = \frac{8*m*m*m*n*n}{4*m*n*n*n} = \frac{8}{4}*\frac{m*m*m}{m}*\frac{n*n}{n*n*n}\]

    now just cancel stuff.

    Rules for multiplying terms with exponents are pretty few and simple. First the base has to be the same such as x or y etc. if you are multiplying like \[x ^{3}\times x ^{2}=x ^{5} \]

    You can also make this a bit less tedious by using: \[\frac{8m^3n^2}{4mn^3} = \frac{8*m*m^2*n^2}{4*m*n*n^2}\]

    Then cancel stuff that has the same power. But eventually you'll realize that you're just subtracting the exponents on the bottom from the exponents on the top (or adding negative exponents).

    Polpak, how do you get that line in your fractions (the long line??

    good question i wish i knew it would make typing the equations out alot easier

    Well I don't use the equation editor cause it causes issues so I type them all by hand. The syntax they use here is called latex, and for doing fractions you just have \frac{numerator}{denominator}

    No you have to put it in the equation format. All equations must be surrounded by \ [ \] (but no spaces betwen the \ and the [)

    It should be \[\frac{2m^2}{n}\]

    So you have it right for m and n, just forgot to divide the leading coefficients.

    Also when typing negative exponents in latex you have to use n^{-1}
