Currently the denominator is [tex]8x^4y^3z[/tex]. If you want to move those up so they sit with the numerator, then what you have to do is make the exponents negative. You make a negative exponent positive by moving it under a 1; undo that process to make the exponents negative. If we do that, then the expression would be [tex]3a^2b^2c^58 ^{-1} x ^{-4} y ^{-3} z ^{-1} [/tex]
