Question

Rút gọn phân thức:

a) 10x³y² / 20xy⁵

b) 15x (x + 5)² / 20x (x +5)

Answer 1

\(a,\dfrac{10x^3y^2}{20xy^5}=\dfrac{x^2}{2y^3}\\ b,\dfrac{15\left(x+5\right)^2}{20x\left(x+5\right)}=\dfrac{3\left(x+5\right)}{4x}\)

Answer 2

a) \(\dfrac{x^2}{2y^3}\)

b) \(\dfrac{3\left(x+5\right)}{4}\)=\(\dfrac{3x+15}{4}\)

Answer 3

a) \(\dfrac{10x^3y^2}{20xy^5}=\dfrac{x^2}{y^3}\)
b) \(\dfrac{15x\left(x+5\right)^2}{20x\left(x+5\right)}=\dfrac{x+5}{5x}\)
