2x • 2xy • -x to the second power

4x⁴y  

Step-by-step explanation:

Square the -x

2x·2xy·(-x)²= 2x·2xy·x²

Use the  commutative property of multiplication to rearrange the order

2x·2xy·x² = 2·2·x·x·x²·y

Use the  associative property of multiplication to combine like terms

2·2·x·x·x²·y = ( 2·2)·(x·x·x²)·y

Simplify

( 2·2)·(x·x·x²)·y = 4x⁴y
