Question

type the missing number.
hint: use the associative property of multiplication.
(□ × 7) × 2 = 9 × (7 × 2)
submit

Explanation:

Step1: Recall associative property

The associative property of multiplication states that \((a\times b)\times c = a\times(b\times c)\) for any real numbers \(a\), \(b\), and \(c\).

Step2: Apply the property to the equation

We have the equation \((\square\times7)\times2 = 9\times(7\times2)\). Comparing with the associative property \((a\times b)\times c=a\times(b\times c)\), we can see that \(a\) should be equal on both sides. Here, \(b = 7\) and \(c=2\), so the missing number (which is \(a\) on the left - hand side) should be equal to \(9\) (which is \(a\) on the right - hand side).

Answer:

\(9\)
