problem of solving



Hi!
Using Maxima i was trying to solve the following problem

solve it for M
(exp(P*(T-t)*M^a)-1)/(exp(F*(T-t)*(L-M)^b)-1)=(a/b)*((L-M)/M)

and
got the result like this
[M=(a*L*(%e^(F*(L-M)^b*T-t*F*(L-M)^b)-1))/(b*%e^(M^a*P*T-t*M^a*P)+a*(%e^(F*(L-M)^b*T-t*F*(L-M)^b)-1)-b)]


what does % mean here?
am i committing any error while trying to solve it, if so. how can i solve
this?
please help.
with regards
