  1. Sir we can do it just by finding E(25) = 20 ; also as 13 & 17 are coprime to 25 ; so 13^20 / 25 = rem. 1 ; so 13^100 / 25 = rem 1 ; again rem(17^100 /25) = 1 ; so total remainder is 2 ; What's your take on this method sir ? Kindly don't mind if i have done some mistake . & sir ; this is less time consuming also i guess .
