Textbook Question
Identify the property illustrated in each statement. Assume all variables represent real numbers. 5(t+3) = (t+3)∙5
Verified step by step guidance1
Observe the given equation: \$5(t+3) = (t+3) * 5\(. This shows that the order of multiplication between the number 5 and the expression \)(t+3)$ can be switched without changing the result.
Recall the properties of real numbers, specifically the Commutative Property of Multiplication, which states that for any real numbers \(a\) and \(b\), \(a \times b = b \times a\).
Compare the given equation to the Commutative Property of Multiplication: here, \(a = 5\) and \(b = (t+3)\), so \$5(t+3) = (t+3)5$ fits the property exactly.
Conclude that the property illustrated by the equation \$5(t+3) = (t+3) * 5$ is the Commutative Property of Multiplication.
Remember that this property allows us to multiply numbers or expressions in any order without affecting the product.
