rút gọn phân thức

\(\dfrac{5a^2\left(a+b\right)^3}{10a\left(a+b\right)^2}\)

Answer 1

\(\dfrac{5a^2\left(a+b\right)^3}{10a\left(a+b\right)^2}=\dfrac{a\left(a+b\right)}{2}\)

Answer 2

\(\dfrac{5a^2\left(a+b\right)^3}{10a\left(a+b\right)^2}=\dfrac{a\left(a+b\right)}{2}\)

Answer 3

\(\dfrac{5a^2\left(a+b\right)^3}{10a\left(a+b\right)^2}\) = \(\dfrac{a\left(a+b\right)}{2}\) = \(\dfrac{a^2+ab}{2}\)
