Methods to find the square root of 4761

There are three methods to find the square root of 4761

• Prime factorization method
• Long division method
• Repeated subtraction method.

Prime factorization method

Prime factorization to find the square root is used to find only those numbers that are perfect squares. n is the prime factor. When the prime factors of the number are found the similar factors are squared as n². After taking a square on both sides the root with a square is canceled. 

• Step 1: Find the prime factors of the given number
  Prime factors of 4761 =  3 x 3 x 23 x 23
• Step 2:  Take the similar factors, by multiplying them we get the square root
  4761 = 3 x 23 = 69
  The exponential form can be written as,
  4761 = 3² x23².
  Next, take square on both side
  √4761 = (√3)² x (√23)²
  √4761 = 3 x 23 = 69
  Hence, the square root of √4761 = 69.

Long division method

Finding the square root of a perfect square number using the long division method is simple. The number that divides 4761 completely is the square root of the number. Find the nearest possible number that can divide by 4761 and continue till you reach zero.  

Long division for the square root of 4761

Hence, √4761 = 69.

Repeated subtraction method

Repeated subtraction can be used to find the square root of any perfect squares. In this case, the given number is a four-digit number. Finding higher digits can be time-consuming and hard to solve.

Students can use repeated division for 2 or 3-digit numbers. Hence, long division and prime factors can be used to find the square root of higher numbers. 

Solved Examples

Example 1: What is the value of 64 when multiplied by 4761?
Solution:
The square root of 64 = 8
Therefore, by multiplying 8×69 =552
Hence the value of 64 when multiplied by √4761 = 552.
Example 2: What is the area of the square whose each side is equal to 69 cm?
Solution:
Area of the square = x²
Here x= 69
Therefore, 692 = 69× 69 = 4761
Hence the are of the square with 69 cm = 4761 sq. cm
Example 3: Find the perimeter of the square if the area of the square tile is 4761.
Solution:
The area of the square = 4761.
The side length of the tile = √area
Therefore, √4761 = 69
A square has 4 sides, by multiplying 69× 4 we get 276.
Therefore the perimeter of the tile = 276 units
Example 4: Find the square root of 4761 using the long division method.
Solution:

Hence, √4761 = 69.
Example 5: What is the square root of 4761 using the prime factor
Solution:
Prime factors of 4761 =  3 x 3 x 23 x 23
By multiplying them we get the square root
4761 = 3 x 23 = 69
Hence, √4761 = 69
