What Is the Square Root of 53?
The square root of a number n is written as √n. This number when squared or multiplied by itself results in the original number n. The square root of 39 can be written as:
 Radical form: √53
 Decimal form: 7.280
 Exponent form: (53)^{1/2}
Is Square Root of 53 Rational or Irrational?
 53 is a number that is not a perfect square, meaning it does not have a natural number as its square root.
 Square root of 53 is simlipfied in decimal form as √53 = 7.280.
 Square root of 53 cannot be expressed as a fraction in the form p/q which tells us that the square root of 53 is an irrational number.
How to Find the Square Root of 53?
There are 2 ways to find the square root of 53:
 Long Division Method
 Prime Factorization
Long Division Method
The square root of 53 by long division method consists of the following steps:
 Step 1: Starting from the right, we will pair up the digits 53 by putting a bar above 53. We also pair the 0s in decimals in pairs of 2 from left to right.
 Step 2: Find a number that, when multiplied to itself, gives a product less than or equal to 53. The number 7 fits here as 7 squares gives 49. Dividing 53 by 7 with quotient as 7, we get the remainder as 4.
 Step 3: Drag a pair of 0s down and fill it next to to make the dividend 400.
 Step 4: Double the divisor 7, and enter 14 below with a blank digit on its right. Think of a number which is greater than equal to dividend, i.e., 400. 142 is the perfect number to divide 400.
 Step 5: Multiply 142 by 2. 142 × 2 = 284 < 400 and write the remainder, i.e., 116.
 Step 6: Repeat this process until the quotient starts repeating after certain digit.
Therefore, the square root of 53 = 7.280
Prime Factorization
 To find the square root of 53, we shall first express it in terms of its prime factors.
Prime factorization of 53 = 1 × 53  Since all the prime factors of 53 are unique none of these factors are perfect squares, the square root of 53 cannot be simplified.
 Therefore, the Square Root of √53 = 7.280

Solved Examples

Example 1: Rob is multiplying a number by itself. If the product is 53, help Rob in finding the number.
Solution:
To find the number let us assume number = y
On multiplying y times y = y × y = 53
y² = 53
y = √53
y = 7.280
(7.280 × 7.280 = 52.999 ≅ 53)
The number is 7.280. 
Example 2: The area of a squareshaped table is 2809 square units. Calculate the measurement of one side of the table.
Solution:
The area of table = 2809 sq. units
To find the side of the squareshaped table, let us take square root of 2809 by prime factorization method.
2809 = 1 × 53 × 53
Square root of 2809 is 53.
Therefore, side of square table is 53 units.
