Question

Answer 1

a) \(5\left(x-y\right)^5:2\left(x-y\right)^2\)

\(=\dfrac{5\left(x-y\right)^5}{2\left(x-y\right)^2}\)

\(=\dfrac{5\left(x-y\right)^3}{2}\)

\(=\dfrac{5}{2}\left(x-y\right)^3\)

b) \(4\left(x+y-z\right)^5:12\left(x+y-z\right)^3\)

\(=\dfrac{4\left(x+y-z\right)^5}{12\left(x+y-z\right)^3}\)

\(=\dfrac{\left(x+y-z\right)^2}{3}\)

\(=\dfrac{1}{3}\left(x+y-z\right)^3\)
