Hello SymPy users and devs,
I have a large expressions with
- [image: $\log^2(\frac{R}{R_1})$] split into [image: $\log^2(R) - 2
\log(R) \log(R_1) + \log^2 (R_1)$], and
- [image: $\log^3(\frac{R}{R_1})$] split into [image: $\left [ \log(R) -
\log(R_1)\right ]^3 = \ldots$]
I want to combine logs (so to make it more readable).
I think I need to factor the thing first, but factor fails and powsimpmakes it
even worse.
Here's an image of the of the expression:
[image: $$\Gamma_{R}^{2} R^{4} R_{1}^{2} + 4 \Gamma_{R}^{2} R^{2}
R_{1}^{4} \log^{3}{\left (R \right )} - 12 \Gamma_{R}^{2} R^{2} R_{1}^{4}
\log^{2}{\left (R \right )} \log{\left (R_{1} \right )} - 8 \Gamma_{R}^{2}

\right )} + 2 P^{2} R^{2} - 2 P^{2} R_{1}^{2}$$]
My question: is there a way to combine logs in this case?
