Square root of 529 is 23 and is represented as √529 = 23.
Consider the numbers 25, 36, 49… These are obtained by multiplying a number with itself. i,e 25 = 5 × 5, 36 = 6 × 6 and 49 = 7 × 7 and so on. The numbers 25, 36, 49 are termed as perfect square numbers and 5, 6, 7 are termed as square roots for 25, 36 and 49 respectively. If the number 529 is a perfect square, then there will be an integer “y” such that “y ×y” = 529, where “y” will be the square root of 529. Let us determine the value of “y” using different methods that are detailed below.
Note the Following:
The Square root of 529 = √529 where √ = radical, and 529 is the radicand.
Exponential Form of Square root of 529 = 5291/2.

How to Find the Square root of 529?
There are three methods to find the Square root of 529:
- Prime Factorisation method
- Long Division method
- Repeated Subtraction method
Square root of 529 by Prime Factorisation Method
In the Prime Factorisation method, the following steps are followed;
- Divide 529 by prime divisors. Only 23 divided 529.
- Since 23 x 23 is 529, 23 is the square root.
Division for 529 is;

529 = 23 × 23
529 = (23 × 23)
√529 = √(23 × 23)
√529 = 23
Therefore the square root of 529 = 23.
Square root of 529 by Long Division Method
In the long division method, the given numbers are paired in groups, starting from the right side. Let us understand the long division method, in detailed steps;
Step 1: Grouping the given number into pairs
Given number is 529, grouping it as 2 and 56.
Step 2: Consider the first number.
Let us find a square number that divides the first number
i.e 1 × 1 = 1
2 × 2 = 4
3 × 3 = 9.
Step 3: Continue the division using the next number 29. The first number to be used as the next divisor (Divisor of first division multiplied by quotient of first division)
The Division completes with zero remainder. Hence the quotient is the square root, which is 23 for 529.
Square root of 529 by Repeated Subtraction Method.
In the repeated subtraction method, the number 529 is decreased repeatedly by odd numbers. This results in
- Difference = zero; Then 529 is a perfect square with the perfect square root.
- Difference = negative; Then 529 is not a perfect square and it has an irrational root.
