Python | sympy.expand_log() method

With the help of sympy.expand_log(), we can simplify the log terms in the mathematical expression by using the following properties that are listed below.

Properties :
1) log(x*y)=log(x)+log(y)
2) log(x**n)=nlog(x)

Syntax : sympy.expand_log()
Return : Return the simplified mathematical expression.

Example #1 :
In this example we can see that by using sympy.expand_log(), we are able to simplify the log terms in mathematical expression.

# import sympy
from sympy import *

x, y, z = symbols('x y z', positive = True)
gfg_exp = log(x * y)

# Using sympy.expand_log() method
gfg_exp = expand_log(gfg_exp)

print(gfg_exp)

Output :

log(x) + log(y)

Example #2 :

# import sympy
from sympy import *

x, y, z = symbols('x y z', positive = True)
gfg_exp = log(x**3)

# Using sympy.expand_log() method
gfg_exp = expand_log(gfg_exp)

print(gfg_exp)

Output :

3*log(x)
