5. To write a python program find the square root of a number (Newton’s method).

 def newton_sqrt(num):

    guess = num / 2

    while abs(guess * guess - num) > 0.0001:

        guess = (guess + num / guess) / 2

    return guess

# Example usage

num = 25

print(newton_sqrt(num)) # Output: 5.000023178253949
