ANSWER

$8 {x}^{5} {y}^{7} {z}^{2}$

EXPLANATION

The given expression is

$2 {x}^{2} {y}^{3} {z}^{2} \times 4x {y}^{4} {x}^{2}$

We multiply out to obtain,

$= 2 \times 4 \times {x}^{2} \times x \times {x}^{2} \times {y}^{3} \times {y}^{4} \times {z}^{2}$

Recall that,

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this rule to obtain,

$= 8 {x}^{2 + 1 + 2} {y}^{3 + 4} {z}^{2}$

This simplifies to
$= 8 {x}^{5} {y}^{7} {z}^{2}$
