Where is the m in question stem, check in case you have typed it correctly....

IMO - A If you see powers of 3 when divided by 10 yeild remainders in a pattern 3^1 - remainder 3 3^2 - remainder 9 3^3 - remainder 7 3^4 - remainder 1 3^5 - remainder 3 and the pattern repeats as 3,7,9,1,3,7,9,1 etc therefore 4n+1 powers yeild remainder 3 4n+2 powers yeild remainder 9 etc now from...

Remainder Problem

If n and m are positive integers, what is the remainder when 3^(4n+2) is divided by 10?
(1) n = 2
(2) m = 1

Please, I'm not yet clear about the solution to this problem. I still need more clarification.Thanks

Function/Prime Number Problem

For every positive even integer n, the function h(n) is defined to be the product of all the even integers from 2 to n, inclusive. If P is the smallest prime factor of h(100) +1, then p is a. Between 2 &10 b. Between 10 & 20 c. Between 20 & 30 d. Between 30 & 40 e. Greater than 40
