Question

rút gọn

1, 1/3 x^2 y^5 ( -3/5 x^3 y ) + x^5 y^6

Answer 1

\(\dfrac{1}{3}x^2y^5\left(\dfrac{-3}{5}x^3y\right)+x^5y^6=\dfrac{-1}{5}x^5y^6+x^5y^6=\dfrac{4}{5}x^5y^6\)

Answer 2

1: Ta có: \(\dfrac{1}{3}x^2y^5\cdot\left(-\dfrac{3}{5}x^3y\right)+x^5y^6\)

\(=\dfrac{-1}{5}x^5y^6+x^5y^6\)

\(=\dfrac{4}{5}x^5y^6\)
