In Python, you can write the square root of a number using the `sqrt()`

function from the built-in `math`

module. Here’s an example:

import math x = 16 y = math.sqrt(x) print(y)

Output:

4.0

In this example, we first import the `math`

module using the `import`

statement. Then we define a variable `x`

and set it equal to the number whose square root we want to find. We use the `sqrt()`

function from the `math`

module to calculate the square root of `x`

, and store the result in the variable `y`

. Finally, we use the `print()`

function to display the value of `y`

.

### Using math.pow() function:

Yes, you can also use the `math.pow()`

function to calculate the square root of a number in Python. The square root of a number `x`

can be calculated as `math.pow(x, 0.5)`

. Here’s an example:

import math x = 16 y = math.pow(x, 0.5) print(y)

Output:

4.0

In this example, we again import the `math`

module using the `import`

statement. Then we define a variable `x`

and set it equal to the number whose square root we want to find. We use the `math.pow()`

function with arguments `x`

and `0.5`

to calculate the square root of `x`

, and store the result in the variable `y`

. Finally, we use the `print()`

function to display the value of `y`

.

### Using ** Operator:

Yes, you can also use the `**`

operator to calculate the square root of a number in Python. The square root of a number `x`

can be calculated as `x**0.5`

. Here’s an example:

x = 16 y = x**0.5 print(y)

Output:

4.0

In this example, we define a variable `x`

and set it equal to the number whose square root we want to find. We use the `**`

operator with arguments `x`

and `0.5`

to calculate the square root of `x`

, and store the result in the variable `y`

. Finally, we use the `print()`

function to display the value of `y`

.
