Question

I got an answer of -5m^4-40m^7 do i change the answer to -40m^7-5m^4 becausea the power is laeger???

Answer 1

there is no need to do this but it seems usual from what i've observed.
A good idea would be to factor this expression to -5m^4(8m^3 + 1)

Answer 2

Which can further be factored (using the sum of two cubes) to -5m^4(2m+1)(4m^2-2m+1)

Answer 3

yup
