Question

Could someone show me how to do these?
Divide.

Answer 1

\[(8m ^{7}-10m ^{5})\div2m ^{3}\]

Answer 2

\[ \frac{8m^7 - 10 m^5}{2m^3} \]
when we subtract fractions with the same denominator we do this
\[ \frac{8m^7 }{2m^3} - \frac{10 m^5} {2m^3}= \frac{8m^7 - 10 m^5}{2m^3}\]
in other words, that is two ways to the write the same thing.

simplify each of the two fractions

Answer 3

I assume you know m^7 means m*m*m*m*m*m*m
and when you divide by m*m*m, some of the m's cancel
