Answer

$10\times(x\times y)$

Work Step by Step

The associative law of multiplication states that $a\times(b\times c)=(a\times b)\times c$ (where $a$, $b$, and $c$ are real numbers). That is, changing the grouping of numbers to be multiplied does not affect the answer. Therefore, $(10x)y=(10\times x)\times y=10\times(x\times y)$.
