## How to Calculate Square Root from 1 to 20?

To calculate the square root of numbers from 1 to 20, you can use various methods such as:

**Calculator**: Use a scientific calculator with a square root function to find the square root of each number individually.**Long Division Method**: Apply the long division method to find the square root of each number manually. This involves a step-by-step process of approximation and division.**Prime Factorization**: Decompose each number into its prime factors and then simplify to find the square root.**Estimation**: Make an educated guess of the square root based on the nearest perfect squares and refine the estimate through repeated approximations.

## FAQs

## How do you estimate square roots?’

Estimating square roots involves finding the nearest perfect squares above and below the given number, then making an educated guess between them. For example, to estimate √15, we find that 3² = 9 and 4² = 16, so √15 is between 3 and 4.

## What are the practical applications of square roots?

Square roots are used in various fields such as mathematics, engineering, finance, and physics. They are essential for calculating distances, areas, volumes, and in algorithms for data analysis.

## Why are some square roots irrational?

Square roots of numbers that are not perfect squares result in irrational numbers, meaning they cannot be expressed as fractions. For example, √2 is irrational because it cannot be written as a simple fraction.
