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:

Answer: 512
