Answer
$\frac{2m^4}{n^4}$
Work Step by Step
You have $\frac{10m^6n^3}{5m^2n^7}$.Solve:
$\frac{10m^6n^3}{5m^2n^7}$ -divide what can be divided-
$\frac{2m^6n^3}{m^2n^7}$ -apply exponent rule $\frac{x^a}{x^b}$=$x^{a-b}$-
$\frac{2m^4n^3}{n^7}$ -apply exponent rule $\frac{x^a}{x^b}$=$x^{a-b}$-
=$\frac{2m^4}{n^4}$
