Question

giúp milk bài 2 vs ạ

Answer 1

2:

a: =4ab*4a^4b^2=16a^5b^3

b: =4/9a^2b^2*(-9)*a^2b=-4a^4b^3

c: =-4xy^2z*4x^4y^2=-16x^5y^4z

d: \(=\dfrac{1}{4}\cdot x^3y^2z\cdot4x^4y^4=x^7y^6z\)

e: \(=-\dfrac{2}{3}\cdot\dfrac{9}{4}\cdot xy^2\cdot x^3y^4=\dfrac{-3}{2}x^4y^6\)

f: \(=3xy^4\cdot\left(-5\right)\cdot x^3y\cdot\dfrac{1}{9}x^4y^2=-\dfrac{5}{3}x^8y^7\)

g: \(=-\dfrac{5}{3}\cdot x^5y\cdot9x^2y^8\cdot\dfrac{1}{25}x^6=-\dfrac{3}{5}x^{13}y^9\)
