Python:

```
from sympy.solvers import solve
from sympy import Symbol
import math
x = Symbol('x')
A, B, C, D = 0.59912051, 0.64030348, 263.33721367, 387.92069617
print(solve((A * x) + (B * math.sqrt(x**3)) - (C * math.exp(-x / 50)) - D, x , numerical = True))
```

Code:

```
Traceback (most recent call last):
File "c:/Users/***/Desktop/Python Stuff/***", line 9, in <module>
solve((A * x) + (B * math.sqrt(x**3)) - (C * math.exp(-x / 50)) - D, x , numerical = True)

raise TypeError("can't convert expression to float")
TypeError: can't convert expression to float
```

Why this is happening ?Thanks
