(a) If n is divisible by 6, then n2 is divisible by 6.
Homework Equations
The Attempt at a Solution
For (a) so far I have n=6k and n2=6k, however I am unsure of where exactly I have to go from there?
I think this statement is true because I tested numbers in place of n so I think it is true, but I know that is not enough to determine if it really is true and I am having trouble figuring out the next step.
Thank you.
