Answer
Yes, the expressions are equivalent.
Work Step by Step
Let us simplify the first expression, $m(1-1)$, using the order of operations:
First, we simplify inside the parentheses: $m(0)$
The zero property of multiplication states that the product of any real number and $0$ is $0$.
Next, we multiply using this property: $0$
Since the other expression given is $0$, the two expressions are equivalent.
