Question

(8m^7-10m^5) divided by 2m^3 is.....
Helpp ?/:

Answer 1

well split the numerators into 2 fractions with the same denominators and you get

\[\frac{8m^7}{2m^3} - \frac{10m^5}{2m^3}\]

the index law for division is when the base is the same, subtract the powers.

\[\frac{x^a}{x^b} = x^{a - b}\]

so you need to apply the law to this problem and you need to simplify

\[\frac{8}{2} -=.... and.... \frac{10}{2} =\]

to get the coefficients of m
