(1) k is a positive number.
(2) m is a positive number.

(1) no info on value m....not suff
(2) no info on value k....not suff

combined if m=k=1 then 5m^k < 50k
but if m=20 , k=1 then 5m^k > 50k

not suff

5m^k>5k is equivalent to 5*k*logm>50*k--> K's cancel out, so the problem depends on m regardless of what K is and the inequality is only correct if m is greater than 10^10

1- Not sufficient because K doesn't matter in this problem
2- Not sufficient because we don't know if m is less than or greater than 10^10.

Answer is E.
