I'm trying to solve this equation
$ 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 ?
