Answer:
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
