Python program to find square root of a number by newton's method

🤷‍♂️Hello learners, Welcome back to yet another article on Python. In this article, we are going to learn:

• python program to find square root of a number by newton's method

So let’s get started:

🤷‍♂️🤷‍♂️What is the Newton Square Root formula?

If a given number is N, then its square root can be given by the below formula:

🔓square_root = 0.5 * (Q + (N / Q)) where Q is any guess which can be assumed to be N or 1.

In the given formula We take Q as an assumed square root of N and square_root is the correct square root of N.

 

💻Program For finding Square root using Newton's Method:

Given below is python program to find square root of a number by newton's method:

def newtonSqrt(n, base):
    approx_root = 0.5 * n
    for i in range(base):
        betterapprox = 0.5 * (approx_root + n/approx_root)
        approx_root = betterapprox
    return betterapprox

Output

the square root of 100 : 10.0
the square root of 256 : 16.0
the square root of 24 : 4.898979485566356

🧐In this Program base is the base of number we are going to find whether it is binary,decimal or hexadecimal.
