Question

Find the counterexample to this statement: If ab = 3, then either a or b must be equal to 3

Answer 1

You want 2 numbers so that their product is 3. Can you find two such numbers without either of them being 3?

Answer 2

For example, a = 0.5, b= 6. Assuming a and b don't have to be integers.

Answer 3

As 0.5 * 6 = 3.

Answer 4

So you're saying that I just have to come up with 2 numbers that make 3..
