This is a homework problem my 5th grade son has got in his accelerated math class and I have no clue as to how to proceed.
the two positive integer solutions of the equation
x -mx + n = 0 are k and t where m an n are primes and k > t. What is the value of m^n +n^m + k^t + t ^k.

Could use some help

Thank you M(s/r) peppers18 and Mr Khan.
I think I can take it from there.
I was helpless and felt hopeless when I saw my son's blank face. Thanks again.

That is clever!!!

when you factor x-mx+n=0, you are looking for factors of n whose sum is m. well, since n is prime, the factors are n and 1. so the sum is m=1+n. since m and n are both primes, which 2 primes make this equation work?

see what you can do from this

This is a fifth grade problem?!!

I feel so inadequate - I have no idea where to even begin!!!
