Question

complete the expressions, write each answer as a num 5a·3 = □·5a commutative proper = multiply

Explanation:

Step1: Apply Commutative Property of Multiplication

The commutative property of multiplication states that \(a\times b = b\times a\). So for \(5a\times3\), we can rewrite it as \(3\times5a\).

Step2: Multiply the Coefficients

Multiply the coefficients 3 and 5. \(3\times5 = 15\), so \(3\times5a=15a\).

Answer:

First blank: 3; Second blank: \(15a\)
