Answer
$14\times(z\times y)$
Work Step by Step
The associative property of multiplication holds that $(a\times b)\times c=a\times(b\times c)$.
In this example, we can set $(a\times b)\times c=(14\times z)\times y$.
Therefore, $a=14$, $b=z$, and $c=y$, so an equivalent expression would be $a\times(b\times c)=14\times(z\times y)$.
