Question

Reciprocal property of multiplication
What property is 5+ac=5+ca

Answer 1

reiprocal property is also known as the commutiave property which staes
ab=ba so we have
5+ac=5+ca
we can ignore the 5 since it was no changed
ac=ca
very close to
ab=ba
aka commutative property

Answer 2

This is the commutative property of multiplication. Commutative property has to do with order. Whereas the equation begins with 5+ac, its equivalent reads 5+ca. The order of the variables has changed.
