# Python | sympy.expand_pow_exp() method

With the help of sympy.expand_pow_exp() method, we can expand mathematical expression using following identity –

` x(a+b) = xa.xb`

Syntax: expand_pow_exp(expression)
Parameters:
expression – It is the mathematical expression which needs to be expanded.

Returns: Returns an expended mathematical expression corresponding to the input expression.

Example #1:
In this example we can see that by using sympy.expand_pow_exp() method, we can expand a mathematical expression in terms of power.

 `# import sympy ` `from` `sympy ``import` `*`  ` `  `x, a, b ``=` `symbols(``'x a b'``) ` `expr ``=` `x``*``*``(a ``+` `b) ` ` `  `print``(``"Before Expansion : {}"``.``format``(expr)) ` `   `  `# Use sympy.expand_pow_exp() method ` `smpl ``=` `expand_pow_exp(expr)  ` `   `  `print``(``"After Expansion : {}"``.``format``(smpl))  `

Output:

```Before Expansion : x**(a + b)
After Expansion : x**a*x**b
```

Example #2:

 `# import sympy ` `from` `sympy ``import` `*`  ` `  `x, a, b ``=` `symbols(``'x a b'``) ` `expr ``=` `x``*``*``(``2` `*` `a ``+` `3` `*` `b) ` ` `  `print``(``"Before Expansion : {}"``.``format``(expr)) ` `   `  `# Use sympy.expand_pow_exp() method ` `smpl ``=` `expand_pow_exp(expr)  ` `   `  `print``(``"After Expansion : {}"``.``format``(smpl))  `

Output:

```Before Expansion : x**(2*a + 3*b)
After Expansion : x**(2*a)*x**(3*b)
```
