How did you get that? You need to be careful when you are using symbols ^ and x

Can you express 1 as a power of 11? (Note:**by power here we mean repeated application of group operation so 11^5 = 5**). Say it is 'n'

Once you know that ф(1)= ф(11^n) = ф(11)^n

Once we know ф(1), ф(x) should be easy, right?
