giúp vs ạ !!!

Answer 1

a: \(=\left(2\cdot\dfrac{4}{3}\cdot6\right)\cdot x\cdot x^2\cdot x\cdot y^2\cdot y^3=16x^3y^5\)

Bậc là 5

b: \(=\left(\dfrac{4}{3}\cdot\dfrac{3}{4}\right)\cdot x^2\cdot x\cdot y^2\cdot y\cdot z^2\cdot x=x^3y^3z^3\)

Bậc là 9

c: \(=\left(-4a^2\cdot4b^2\cdot\dfrac{-1}{4}\right)\cdot x\cdot x^2\cdot x^2\cdot y^2\cdot y^3=4a^2b^2x^5y^5\)

Bậc là 10
