The sqrt() is a built-in math library function in Python that returns the square root of x for x > 0. To use the sqrt() method, **import math module**. We can import the math module and then call the sqrt() function to get the square root of any given value.

These modules are not written in Python but in C. You can find them (at least on linux) **in a subfolder of the lib-folder called lib-dynload**. The math module is then in a file math.cpython-33m.so (on windows probably with .

**sqrt() function is an inbuilt function in Python programming language that returns the square root of any number**. Syntax: math. sqrt(x) Parameter: x is any number such that x>=0 Returns: It returns the square root of the number passed in the parameter.

To Import math in python is **to give access to the mathematical functions, which are defined by the C standard**. In this tutorial, you will learn about some important math module functions with examples in python.

The math module is a standard module in Python and is always available. To use mathematical functions under this module, you have to import the module using import math . **It gives access to the underlying C library functions**.

The sqrt() is a built-in math library function in Python that returns the square root of x for x > 0. To use the sqrt() method, **import math module**. We can import the math module and then call the sqrt() function to get the square root of any given value.

Exponentiation (b^{n}) is **the mathematical operation that multiples a number (b) a certain number of times (n) with itself**. There are three ways to program that behaviour in Python. The power operator ( ** ) raises the left value to the power of the second value. For example: 2 ** 3 .

**File >> Settings >> Project interpreter**. You should see a list of currently installed packages/libraries. If the module is not specified in there click the plus sign and look for your module in there. Also make sure you specify it correctly when you import it.

sqrt(25)) output of above code will be **5.0**. If you go on solving the questions in modules section, You will come across this.

You have two options: import math math.sqrt() will **import the math module into its own namespace**. This means that function names have to be prefixed with math .

numpy. sqrt(array) function is **used to determine the positive square-root of an array, element-wise**. Syntax: numpy.sqrt() Parameters: array : Input values whose square-roots have to be determined.

As from ancient period to today people have been using numbers **for calculations and many things**. They are used every where from our ages to weighing things in market we use numbers. If there will be no numbers then we will face many difficulties as all fields require numbers.

**10 Ways We Use Math Everyday**

- Chatting on the cell phone. Chatting on the cell phone is the way of communicating for most people nowadays.
- In the kitchen. Baking and cooking requires some mathematical skill as well.
- Gardening.
- Arts.
- Keeping a diary.
- Planning an outing.
- Banking.
- Planning dinner parties.

**Python Modules**

- Save this code in a file named mymodule.py.
- Import the module named mymodule, and call the greeting function:
- Save this code in the file mymodule.py.
- Import the module named mymodule, and access the person1 dictionary:
- Create an alias for mymodule called mx :
- Import and use the platform module:

Surds are square root values that cannot be reduced further into whole numbers or integers.

Surds can be a square root, cube root, or other root and are used when detailed accuracy is required in a calculation. For example **the square root of 3 and the cube root of 2 are both surds**. 5 ≈ 2.23606 \sqrt{5} \approx 2.23606 5 ≈2.23606, which is an irrational number. The square root of 5 is a surd.

**How to use the Pythagorean theorem**

- Input the two lengths that you have into the formula.
- After the values are put into the formula we have 4²+ 8² = c²
- Square each term to get 16 + 64 = c²
- Combine like terms to get 80 = c²
- Take the square root of both sides of the equation to get c = 8.94 .

**Squares are the numbers, generated after multiplying a value by itself.** **Whereas square root of a number is value which on getting multiplied by itself gives the original value**. Hence, both are vice-versa methods. For example, the square of 2 is 4 and the square root of 4 is 2.

**The sqrt(x) function is used to get the square root of the given number in Python**. The sqrt() function is the part of math module so you need to import it before using in Python program. The value of x must be greater than 0. Square root example.

10 is much closer to 9 than to 16. √10 is therefore **closer to 3 than 4**.

**The square root of 2 is not an imaginary number, it is an irrational number**. Imaginary number: a complex number that can be written as a real number multiplied by the imaginary unit, i (the square root of -1). Irrational number: a real number which cannot be written as a simple fraction.
