Methods to Find Value of Root 98

There are several methods to find the value of the square root of 98:

Prime Factorization Method: Decompose 98 into its prime factors (2 × 7× 7). Take the square root of perfect squares within these factors (2) and multiply them together. The result is the square root of 98.

Estimation Method: Recognize that 98 is between the squares of two consecutive integers (9^2 = 81 and 10^2 = 100). Estimate that the square root of 98 is between 9 and 10, then refine the approximation through trial and error or other numerical methods.

Long Division Method: Employ the long division method to approximate the square root of 98. This involves a step-by-step process of division similar to long division for whole numbers.

Calculator or Software: Utilize a calculator or mathematical software to directly compute the square root of 98. Most modern calculators and software have built-in functions to find square roots.

Square Root of 98 by Long Division Method

Square Root of 98 by Long Division Method

Step 1: Set Up: First, pair the digits of the number from right to left. Since 98 is a two-digit number, it will be treated as one pair, 98.

Step 2: Initial Guess: Start by finding the largest square number less than or equal to 98. The largest whole square less than 98 is 81, which is 9²
Subtraction: Subtract 81 from 98, which gives you 17.

Step 3:Bring Down Next Pair: Normally, you would bring down the next pair of digits, but since there are no more digits, you append a pair of zeros to the remainder, making it 1700.

Step 4: Finding the Next Digit
After subtracting 81 from 98 and bringing down a pair of zeros, we have 1700 as the new dividend. The divisor at this point is 9, which we then double. The doubled divisor is 18. Now, we need to find the next digit, which we’ll call Y. The number Y should be the highest digit such that 18Y×Y is less than or equal to 1700.

Step 5: Repeat Process: Place Y beside 18 making it 18Y, then multiply it by Y and subtract the result from 1700. Repeat this process by bringing down more pairs of zeros and continue the division.

Step 6:Continuation and Precision: You can continue this process to get more decimal places, each time bringing down a pair of zeros and finding the next digit.

98 is Perfect Square root or Not?

No, 98 is not a perfect square.

A perfect squares is a number that can be expressed as the product of an integer multiplied by itself. For example, 9 is a perfect square because 3 × 3 = 9. However, there is no integer that, when multiplied by itself, gives 98. Therefore, 98 is not a perfect square.
