Multiply each of the following expressions.

$2x^{2}\left(3x + 4x^{2}y\right)$
Answer (a):
$6x^{3} + 8x^{4}y$

$\left(x^{3}y^{2}\right)^{4}\left(x^{2}y\right)$
Hint (b):
Remember that the 4th power means to use the expression as a multiplier four times.
$\left(x^{12}y^{8}\right)\left(x^{2}y\right)$
More Help (b):
How can you rewrite this using the Commutative and Associative Properties of Multiplication to simplify it further?
