Question

Rút gọn phân thức: 

\(\frac{14xy^5\left(2x-3y\right)}{21x^2y\left(2x-3y\right)^2}\)

Answer 1

\(=\frac{2.7.xy.y^5\left(2x-3y\right)}{3.7.xy.x\left(2x-3y\right)^2}=\frac{2y^5}{3x\left(2x-3y\right)}\)

Answer 2

\(\frac{14xy^5\left(2x-3y\right)}{21x^2y\left(2x-3y\right)^2}\)

\(=\frac{2y^4}{3x\left(2x-3y\right)}\)

Answer 3

\(\frac{14xy^5\left(2x-3y\right)}{21x^2y\left(2x-3y\right)}\)

\(=\frac{2y^4}{3x\left(2x-3y\right)}\)
