Suppose I am dividing 4^30-2^50
by 5
.
I do understand that 4^30
will get converted to 2^60
I could also find the series of remainders for 2^x
. It comes out to be 2 4 3 1
By that, I could find (4^30) % 5 = 1
and (2^50) % 5 = 4
. But how do I find the combined mod?
i.e. [(4^30)-(2^50)] % 5 = ?
Thank you.
P.S. Please note that by %
, I mean mod
operator.
