Cant solve this math or understand this. Can anyone explain easily ?
is the answer 0?
yes its 0 but I need to know the explanation
simple, when you keep multiplying 13x13 you can see the pattern that the numbers end with 3 9 7 1 and 3 9 7 1 so the end at 17th position you see the number 3 comes
similarly, with 17 multiplying 17 times you find the pattern 7 9 3 1 and at 13th position you find number 7 so, just imagine at large scale when you adding this numbers ending with 7 and 3 you get 10 where ones digit is 0 which is divisible by 10 and hence the number is divisible you can say that the remainder is 0.
