I'm not sure if you've stated the question correctly, but if you have, then the answers are the five complex quintic roots of 14, since 15 is the root of the linear equation given. After finding the real fifth root of 14 (i.e. 14^0.2) you can get the others by repeatedly multiplying by exp(2*pi*i/5)
Note added after reading the other answers: I am essentially answering a different question than they are, because your statement of the question was ambiguous. I think that my question is more interesting, which probably means the other interpretation is correct! But next time, try to write the question so that it can be understood.

first, assuming that the 4 is not under the fifth root, add 4 to both sides of equation.. giving
(x-10)^(1/5) = 4
raise both sides to the fifth power.
giving x-10 = 4^5
solve for x.
x = 10 + 4^5
your final anser is 1034
