$ 3(2.2+(\frac{64}{r})^{(1/3)})= 4(2.2+(\frac{128}{r-1})^{(1/4)})$ using solve function
I want to obtain the numerical solution
**but when i use `sol[0].n(30)`**
**TypeError:** cannot evaluate symbolic expression numerically
**when i try to `find_root(0,1,r)`**
**ValueError:** negative number to a fractional power not real
How to find the solution of this expression ?
