Question

1/2*x^2.(-2*x^2*y^2*z),(-1/3)*x^2*y^3

giup mk voi a 

Answer 1

`1/2x^2(-2x^2y^2z).(-1/3)x^2y^3`

`=1/2 .(-2).(-1/3)x^{2+2+2}.y^{2+3}.z`

`=1/3x^6y^5z`

Answer 2

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

\(=\left(\dfrac{1}{2}\cdot2\cdot\dfrac{1}{3}\right)\cdot\left(x^2\cdot x^2\cdot x^2\right)\cdot\left(y^2\cdot y^3\right)\cdot z\)

\(=\dfrac{1}{3}x^6y^5z\)
