The multiplication property of zero states that the product of any number and 0 is 0. what must be true about either a or b to make ab=0

What properties allow transformation to be used as a problem solving tool

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
