$(5\times7)\times x$

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 $a \times (b\times c)=5\times(7\times x)$. Therefore, $a=5$, $b=7$, and $c=x$, so an equivalent expression would be $(a\times b)\times c=(5\times7)\times x$.
