Question

type the missing number.
hint: use the associative property of multiplication.
(88 × \square) × 90 = 88 × (18 × 90)
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 to given equation

In the equation \((88\times\square)\times90 = 88\times(18\times90)\), comparing with the associative property formula \((a\times b)\times c=a\times(b\times c)\), we can see that \(a = 88\), \(b=\square\), \(c = 90\) on the left - hand side and \(a = 88\), \(b = 18\), \(c=90\) on the right - hand side. So, by the associative property, \(\square\) should be equal to \(18\).

Answer:

18
