√98 = 9.899494, clearly, this is non-terminating and also the decimal part has actually no repeating pattern. Thus, it is not a rational number. √98 is an irrational number.
We can find the square root of 98 making use of assorted approaches.Repeated subtraction Prime factorizationEstimation and also approximationLong division
Square Root of 98 by Prime Factorization
The prime factorization of 98 is 2 × 7 × 7. We can watch that 7 is the only pair of the very same numbers. Hence, 98 cannot be streamlined any further and therefore, √98 is 7√2.
Square Root of 98 by Long Division Method
The value of the square root of 98 by the lengthy department technique consists of the following steps:
Step 1: Starting from the right, we will certainly pair up the digits by placing a bar over them.
Tip 2: Find a number such that as soon as you multiply it with itself, the product is much less than or equal to 98. So, the number is 9. Keeping the divisor as 9, we acquire the quotient as 9 and the remainder 98 - 81 = 17.
Tip 3: Double the divisor and also enter it with a empty on its ideal. Guess the largest possible digit to fill the empty which will additionally end up being the new digit in the quotient, such that once the brand-new divisor is multiplied to the brand-new quotient, the product is much less than or equal to the dividend. Divide and write the remainder.
