This is what I am getting: In [1]: a,y=var('a y') In [2]: simplify(a*y**5) Out[2]: 5 a⋅y In [3]: simplify(y**5/a) Out[3]: 5 y ── a Which git commit are you using? If you do: $ git branch -v aaron 16995ea Changed Mul class so that it does not automatically combine expononts, unless the exponents are numbers or if the combined exponent would not be an Add (e.g., exp(x)*exp(2*x) still goes to exp(3*x). This DOES NOT fix failed tests. It is a preliminary patch. chris 9574270 Solvers: solutions past linear factor found in tsolve fabian 5109fd5 Allow Function.eval to return non-instances of Basic. logic 02bfaa7 Allow Function.eval to return non-instances of Basic. luke 686a377 Proof of concept luke2 105ba8f fix * master a4a8832 Typo fixed in doc/src/guide.txt (thanks to Toon Verstraelen) odes-stable cded981 Finished up first order homogeneous differential equations. They now properly return an Integral class if the equation cannot be solved explicitly. Also, I added a ton of tests (every one from my text!). special dfb5062 jn_zeros implemented and tested sqrt 0d4116a Fix for the other issue toon 0462e0c Allow SYMPY_TEST_CLEAN_TEMP=never it prints all branches that you have + their hashes. You are on the branch with "*", in my case master.
