Question

how do you rewrite using only positive exponents
-3m^-2n^-4

Answer 1

So it's this? \[\large -3m^{-2}n^{-4}\]

Answer 2

oops yeah im wrong. wrong typo.
-3/(m^2n^4)

Answer 3

If it's this:\[\large -3m^{-2}n^{-4}\]then you can simply convert it to a fraction with positive denominators:\[\large \frac{-3}{m^{2}n^{4}}\]

Answer 4

(that should read: positive exponents in the denominators)

Answer 5

do you understand it ?

because x^(-1) = 1/x

ok ?
