i was trying to solve the following problem in Maxima solve for M where (exp(P*(T-t)*M^a)-1)/(exp(F*(T-t)*(L-M)^b)-1)=(a/b)*((L-M)/M) where other that t everything is constant.

while trying to solve it with the help of Maxima i got the result like this

[M=(a*(%e^(F*(1-M)^b*T-t*F*(1-M)^b)-1))/(b*%e^(M^a*P*T-t*M^a*P)+a*(%e^(F*(1-M)^b*T-t*F*(1-M)^b)-1)-b)]

my questions are - 1.what does symbol % mean here? 2. am i committing an error to solve the problem, if so, how can i solve it?
