Answer 2

Answer:

z + nm

Explanations:

The given expression is:

mn + z

Note that:

Commutavity is when changing the position of the operator does not affect the expression

Addition and multiplication are commutative

mn is the same as nm

mn + z is the same as z + nm

The equivalent expression is therefore z + nm
