A table of square roots is a tabular form that shows all the natural numbers from 1 to 100, each approximating to 3 places of decimal. By taking into use this table of square roots, we are able to find the square roots of numbers, less than 100. You can use this table to identify both the squares and square roots of numbers from 1 to 100. Find below the square root table 1 to 50 for your better understanding.

Uses and Application of Root Table Math
We can use the table of square roots for the purpose of estimating the squares and square roots of natural numbers from 1 to 100 as well as square roots of larger numbers.
We can also use square root tables to identify the approximate value of square roots.

Importance of Application of Root Table
We apply a long division method in order to find approximate values of square roots. The method is not only lengthy but quite difficult too. Thus, for the reason, tables of square roots and cube roots have been prepared that register these approximate values of square roots for different numbers.
How to Use Square Root Tables?
Let's take a look at how we use these square root tables. Seeing that we will be obtaining approximately values only, we use the symbol ~ to signalize the same. Values of square roots from the natural number 1 to 99 are provided in the given table up to 3 places of decimal.
A square root of a number ‘m’ is a number x such that x2= m. This is to say, a number x whose square (the outcome of multiplying the number by itself, or x × x) is ‘m’. For example,
Square of 5 i.e. 52 = 25
Square root of 5, √5 = 2.2361
Example of Finding The Square Root
For example, if we want to find the square root of 3500, we would need to look in the middle column of the square root chart until we find the number that is closest to 3500. The number in the middle column that is closest to 3500 is 3464.
Now take a look in at the number to the left of 3464 in order to find its square root. The square root of 3464 is 58.85
Thus, the approximate square root of 3500 is 58.85.
To obtain a more exact number, you can also use a calculator.
Square Roots of Negative Numbers
An ideal way to get square roots of negative numbers is to introduce a completely new form of numbers. Additionally, since we call the sets of integers and decimal numbers as real numbers, we can also strategically launch a new set of imaginary numbers to do something else wholly.
Solved Examples on Square Root
Example1: Evaluate the Square Root of the Number 1764 Using Prime Factorization
Resolve the given number i.e. 1764 into prime factors
While calculating the square root of 1764 using the prime factorization method, we get
2 x 2 x 3 x 3 x 7 x 7 = 1764
Now making the pairs of the similar factors, we get
√1764 = √ [2 x 2] x [3 x 3] x [7 x 7]
= 2 x 3 x 7
Therefore, √1764 = 42
Example 2: Find Out Square Root √5329 Using Long-Division Method.
Solution 2: First we would need to mark periods and apply the long-division method,
7) 53 29 (73
143)143 ( 429
Thus, √5329 =73
