Find the absolute difference of A and B

[dcowboys107]

A B



A and B are whole numbers and neither of which are divisible by 10. If the product of A and B equals 20000, find the absolute value of the difference of A and B.

We know that \(\displaystyle AB = 20000 = 2^5 5^4\). Thus any factor of A or B would be a factor of 20000

But neither A nor B has a factor of 10.
This should tell you what A and B are.
