Python | sympy.sqrt() method
• Last Updated : 04 Jul, 2019

With the help of sympy.sqrt() method, we can find the square root of any value in terms of values and also in terms of symbolically simplified mathematical expression.

Syntax: sqrt(val)

Parameters:
val – It is the value on which square root operation is to be performed.

Returns: Returns square root in terms of values and symbolically simplified mathematical expression corresponding to the input expression.

Example #1:

 `# import sympy ``from` `sympy ``import` `*` ` ` `val ``=` `256``   ` `print``(``"Value : {}"``.``format``(val)) ``     ` `# Use sympy.sqrt() method ``sqrt_val ``=` `sqrt(val)  ``     ` `print``(``"Square root of value : {}"``.``format``(sqrt_val))  `

Output:

```Value : 256
Square root of value : 16
```

Example #2:

 `# import sympy ``from` `sympy ``import` `*` ` ` `val ``=` `8``   ` `print``(``"Value : {}"``.``format``(val)) ``     ` `# Use sympy.sqrt() method ``sqrt_val ``=` `sqrt(val)  ``     ` `print``(``"Square root of value : {}"``.``format``(sqrt_val))  `

Output:

```Value : 8
Square root of value : 2*sqrt(2)
```
