submit

Explanation:

Step1: Recall the commutative property of multiplication

The commutative property of multiplication states that for any two numbers \(a\) and \(b\), \(a\times b = b\times a\).

Step2: Apply the property to the given equation

In the equation \(31\times\square=72\times31\), by the commutative property of multiplication, we can see that the missing number should be \(72\) because \(31\times72 = 72\times31\).

Answer:

72
