Question

Answer 1

a) \(x^3y^6z^3:\left(-x^2y^4z^2\right)\)

\(=-\left(x^3:x^2\right)\left(y^6:y^4\right)\left(z^3:z^2\right)\)

\(=-xy^2z\)

c) \(9x^2y^4z:\left(-\dfrac{1}{4}xy^3\right)\)

\(=\left(9:-\dfrac{1}{4}\right)\left(x^2:x\right)\left(y^4:y^3\right)z\)

\(=-36xyz\)

Answer 2

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

c: \(=\left(9:\dfrac{-1}{4}\right)\cdot\dfrac{x^2y^4z}{xy^3}=-36xyz\)
