How do you calculate square roots?

Square roots can be calculated using several methods:

1. Using a Calculator: Most calculators have a square root function (often represented as √). Simply enter the number and press the square root button.

2. Using Python: You can use the math module in Python:

   import math
   result = math.sqrt(25)  # result will be 5.0
   

3. Using Exponents: The square root of a number can also be calculated using exponents. The square root of (x) is the same as (x^{0.5}):

   result = 25 ** 0.5  # result will be 5.0
   

4. Estimation: For smaller numbers, you can estimate the square root by finding two perfect squares it lies between. For example, since (4^2 = 16) and (5^2 = 25), the square root of 20 is between 4 and 5.

5. Long Division Method: This is a manual method for calculating square roots, which involves a step-by-step process similar to long division.
