divide: \\(\frac{20m^2n^3 - 10m^2n}{5mn}\\)
\\(4m^3n^4 - 2m^3n^2\\)
\\(4mn^2 - 10m^2n\\)
\\(15mn^3 - 5m\\)
\\(4m - 2m\\)

Explanation:

Step1: Split the fraction

$\frac{20m^2n^3}{5mn} - \frac{10m^2n}{5mn}$

Step2: Simplify first term

$\frac{20}{5}m^{2-1}n^{3-1} = 4mn^2$

Step3: Simplify second term

$\frac{10}{5}m^{2-1}n^{1-1} = 2m$

Step4: Combine results

$4mn^2 - 2m$

Answer:

4mn² - 2m
