I need to prove that if are integers then is not possible.
My proof is this:
Since 101010 can be divided with 5 which is prime number, then one of factors also must be 5.
Lets assume that and .
Because it must be then it must be .
So, we have to solve system of equations in order to see whether are integers.
Since is not integer then b is not integer.
Is this proof valid?
