Question

(7xy^2) (y^2-4z) please

Answer 1

Given the expression:

`(7xy^2)(y^2-4z)`

Let's simplify the expression.

Apply distributive property:

`y^2(7xy^2)-4z(7xy^2)`

Solving further:

`\begin{gathered} 7x(y^2y^2)-(4*7)xy^2z \\ \\ 7x(y^(2+2))-28xy^2z \\ \\ 7xy^4-28xy^2z \end{gathered}`

Therefore, the simplified expression is:

`7xy^4-28xy^2z`

ANSWER:

`7xy^4-28xy^2z`
