Question

I need help on this please

Answer 1

The expression we have is:

`2xy\cdot xy^2`

And we are given some values for x and y:

`\begin{gathered} x=2 \\ y=4 \end{gathered}`

The first step will be to substitute the given values into the expression:

`2(2)(4)\cdot(2)(4)^2`

The next step is to solve 4^2 which is equal to 16:

`2(2)(4)\cdot(2)(16)`

And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:

`16\cdot32`

Solving this final multiplication we get the result:

`512`

Answer: 512
