[Maxima-discuss] elementary solve() problem

[richard c. <rp...@cl...>]

Apologies for this very novice question, but what am I doing wrong here? 
Why isn't Maxima giving n=2?

(%i18)	s: t**n;
(s)	t^n
(%i19)	diff(s,t);
(%o19)	n*t^(n-1)
(%i20)	s: t**n;
(s)	t^n
(%i21)	diff(s,t);
(%o21)	n*t^(n-1)
(%i23)	ev(%,t=10) = 2*ev(%,t=5);
(%o23)	n*10^(n-1)=2*n*5^(n-1)
(%i24)	solve(%,n);
(%o24)	[n=0,10^(n-1)=2*5^(n-1)]


Many thanks, Richard
