Square root of 96

The square root of 96 is ±9.79795897113. The positive value,9.79795897113 is the solution of the equation x² = 96.

As defined, the square root is just the inverse of squaring a number, so, squaring 9.79795897113 will result in 96.  The square root of 96 is expressed as √96 in radical form, where the ‘√’  sign is called “radical”  sign. In exponential form, it is written as (96)^1/2  
 

We can find the square root of 96 through various methods. They are:

Prime factorization method

Long division method

Approximation/Estimation method
 

The prime factorization of 96 involves breaking down a number into its factors. Divide 96 by prime numbers, and continue to divide the quotients until they can’t be separated anymore. After factorizing 96, make pairs out of the factors to get the square root. If there exists numbers which cannot be made pairs further, we place those numbers with a “radical” sign along with the obtained pairs

So, Prime factorization of 96 = 3 × 2 ×2×2 ×2 ×2 

for 96, two pairs of factors 2 obtained, but a single 3 and a single 2 are also obtained.

So, it can be expressed as  √96 = √(3×2 ×2× 2 × 2  × 2) = 4√6

4√6 is the simplest radical form of √96
 

This is a method used for obtaining the square root for non-perfect squares, mainly. It usually involves the division of the dividend by the divisor, getting a quotient and a remainder too sometimes.

Follow the steps to calculate the square root of 96:

Step 1 : Write the number 96, and draw a bar above the pair of digits from right to left.

               
Step 2 : Now, find the greatest number whose square is less than or equal to 96. Here, it is9, Because 9²=81 < 96

Step 3 : Now divide 96 by 9 (the number we got from Step 2) such that we get 9 as quotient, and we get a remainder. Double the divisor 9, we get 18 and then the largest possible number A1=7 is chosen such that when 7 is written beside the new divisor, 18, a 3-digit number is formed →187 and multiplying 7 with 187 gives 1309 which is less than 1500.

Repeat the process until you reach remainder 0

We are left with the remainder, 18791 (refer to the picture), after some iterations and keeping the division till here, at this point 

             
Step 4 : The quotient obtained is the square root. In this case, it is 9.797…

Approximation or estimation of square root is not the exact square root, but it is an estimate.Here, through this method, an approximate value of square root is found by guessing.

Follow the steps below:

Step 1 : Identify the square roots of the perfect squares above and below 96

Below : 81→ square root of 81 = 9     ……..(i)

 Above : 100 →square root of 100= 10    ……..(ii)

Step 2 : Divide 96 with one of 9 or 10 

 If we choose 9, and divide 96 by 9, we get 10.666  …….(iii)

             
Step 3: Find the average of 9 (from (i)) and 10.666 (from (iii))

(9+10.666)/2 = 9.8333

Hence, 9.8333 is the approximate square root of 96
 

• Exponential form: An algebraic expression that includes an exponent. It is a way of expressing the numbers raised to some power of their factors. It includes continuous multiplication involving base and exponent.Ex: 3 ⤬ 3 ⤬ 3 ⤬ 3 = 81 or, 3⁴ = 81, where 3 is the base, 4 is the exponent 

• Factorization:Expressing the given expression as a product of its factors Ex: 52=2 ⤬ 2 ⤬ 13 

• Prime Numbers : Numbers which are greater than 1, having only 2 factors as →1 and Itself. Ex: 1,3,5,7,....

• Rational numbers and Irrational numbers: The Number which can be expressed as p/q, where p and q are integers and q not equal to 0 are called Rational numbers. Numbers which cannot be expressed as p/q, where p and q are integers and q not equal to 0 are called Irrational numbers. 

• perfect and non-perfect square numbers: Perfect square numbers are those numbers whose square roots do not include decimal places. Ex: 4,9,25 Non-perfect square numbers are those numbers whose square roots comprise decimal places. Ex :2, 8, 18
