I want to have maple simplify 8ln(6) - 5ln(3) + 10ln(2) - 10ln(5) to ln(7077888/9765625). That is, ln(m/n) where m and n are positive integers. And I want the solution to work for similar expressions with many more terms.
I have tried combinations of expand, simplify, simplify(,ln), and combine. Combine almost works, but produces 40 ln(a/b) where a is the product of fractional powers of integers.
I can do this in sagemath, but would appreciate help doing this in maple.
Solution: What I really care about are the integers m,n. I don't understand why the following works (or is necessary):
a := 8ln(6) - 5ln(3) + 10ln(2) - 10ln(5); a := 8 ln(6) - 5 ln(3) + 10 ln(2) - 10 ln(5)
combine(exp(%)); 7077888 ------- 9765625
