Why Mr Anderson Why ?????????.

Please need help
Can some one explain me what is going on in this two functions ?
why they are not equal ?
-----------------------------------------------------------------------
def Resta(B,N):
    X=3**(N-1)
        result=0
    
    for i in range(10):
        result+= (2**i) * X /(3**i)
    
    return (3**N)-result
--------------------------------------------------------------------
def RestaX(B,N):
    X=3**(N-1)
        result=0
    
    for i in range(10):
        result+=  X * ((2**i)/(3**i))
        
    
    return (3**N)-result
----------------------------------------------------------------------------

This is math.

Then sum( X * a) =  X * sum(a) being X a constant , is it true ????

Why in python is it not true ?

Thanks....
J.A. Martin.
