Hi, I have a sym variable, n. When I run a solve on n, my answer is: ans =
log(23/20, 21452595063076061183/2276332666880001)
How am I supposed to interpret this answer?

log(b, x) represents the logarithm of x to the base b.
So you asked to take the log of 9424.191540720421 with respect to the base 1.15
If you were to show us the original formula (and any constants) we might be able to explain how you got a base of 1.15 .

Thank you!
Also, to convert the symbolic log expression to a numeric value use:
double(sym_ans)
