Giúp mình với ạ

Answer 1

1) 3x³y³    2)-4x³y³z   3)6x³y³   4) 3x⁴y³z²  5)  -5x²y⁷z²

6)12x⁹y¹¹z²

Answer 2

1: \(=3x^2y\cdot xy^2=3x^3y^3\)

2: \(=-3x^2\cdot x\cdot2y^2\cdot y\cdot z=-6x^3y^3z\)

3: \(=2xy^2\cdot3x^2y=6x^3y^3\)

4: \(=\dfrac{3}{2}x^3y^2z\cdot2xyz=3x^4y^3z^2\)

5: \(=\dfrac{5}{2}xy^5\cdot4x^2y^2z^2=10x^3y^7z^2\)

6: \(=\dfrac{14}{5}\cdot\dfrac{15}{7}\cdot4x^6y^8\cdot xy\cdot x^2y^2z^2=24x^9y^{11}z^2\)
