If a number is multiplied by the same number, the result is a square. The inverse of the square is a square root. The square root is used in fields such as vehicle design, finance, etc. Here, we will discuss the square root of 163.

What is the Square Root of 163?

The square root is the inverse of the square of the number. 163 is not a perfect square. The square root of 163 is expressed in both radical and exponential form. In the radical form, it is expressed as √163, whereas (163)(1/2) in the exponential form. √163 ≈ 12.7671, which is an irrational number because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.

Finding the Square Root of 163

The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers such as 163, we use methods like the long-division method and the approximation method. Let us now learn the following methods:

 

  • Prime factorization method 
     
  • Long division method 
     
  • Approximation method

Square Root of 163 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 163 is broken down into its prime factors:


Step 1: Finding the prime factors of 163 Since 163 is a prime number itself, it cannot be broken down further into other prime factors.

 

Step 2: Since 163 is not a perfect square and is already a prime number, calculating its square root using prime factorization is not applicable.

Square Root of 163 by Long Division Method

The long division method is particularly used for non-perfect square numbers. Let us now learn how to find the square root using the long division method, step by step.

 

Step 1: To begin with, we need to group the numbers from right to left. In the case of 163, we need to consider it as 16 and 3.

 

Step 2: Find n whose square is less than or equal to 16. We can say n is '4' because 4 x 4 = 16. Now the quotient is 4, and after subtracting 16 - 16, the remainder is 0.

 

Step 3: Bring down the next pair, which is 3, making the new dividend 3. Add the old divisor with itself, 4 + 4, to get 8 as the new divisor.

 

Step 4: Determine n such that 8n x n is less than or equal to 300 (since we consider two decimal places, the new dividend is 300 after adding zeroes).

 

Step 5: Suppose n = 3, then 83 x 3 = 249.

 

Step 6: Subtract 249 from 300 to get 51. The quotient now becomes 12.7 (approx).

Step 7: Continue these steps until you reach the desired number of decimal places. The square root of √163 ≈ 12.7671.

Square Root of 163 by Approximation Method

The approximation method is another way to find the square roots. It is an easy method to find the square root of a given number. Let's learn how to find the square root of 163 using the approximation method.

 

Step 1: Identify the closest perfect squares around √163. The closest perfect squares to 163 are 144 (122) and 169 (132). √163 falls between 12 and 13.

 

Step 2: Use linear approximation to find the decimal part: (163 - 144)/(169 - 144) = 19/25 = 0.76

Add this decimal to the lower perfect square root: 12 + 0.76 = 12.76

 

Thus, the square root of 163 is approximately 12.76.

Important Glossaries for the Square Root of 163

  • Square root: The operation of finding a number that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, since 4 x 4 = 16.
     
  • Irrational number: A number that cannot be expressed as a simple fraction; it has a non-repeating, non-terminating decimal expansion. For example, the square root of 163 is irrational.
     
  • Prime number: A natural number greater than 1 that has no positive divisors other than 1 and itself. For example, 163 is a prime number.
     
  • Radical expression: An expression that includes a square root, cube root, etc. For example, √163 is a radical expression. 
     
  • Approximation: The process of finding a value that is close enough to the right answer, usually with some understanding of the error involved. For example, √163 ≈ 12.7671 is an approximation.
