Irrational Number : An irrational number is a real number that cannot be expressed as a ratio of two integers

## Methods to Find Value of Root 82

Prime Factorization Method: Express 82 as a product of prime factors and group pairs of similar factors to find the square root of 82.

Estimation Method: Make an initial estimate (e.g., 9) and square it (81). Adjust the estimate based on whether the square is greater or less than 82, refining the estimate until it’s close enough.

Long Division Method: Perform long division to find the square root iteratively, similar to the traditional long division method.

Newton’s Method: Utilize iterative approximation using Newton’s method, which involves refining guesses based on the tangent line to the function curve.

Calculator or Software: Use a calculator or mathematical software capable of computing square roots directly.

## Square Root of 82 by Long Division Method

Step 1: Place a bar over every pair of digits of the number starting from the unit’s place (right-most side). We will have 1 pair, i.e., 82. After 82, we can add zeroes with a decimal point.
Step 2: Divide the left-most number by the largest number whose square is less than or equal to the number in the left-most pair (9 × 9 = 81).
Step 3: Bring down the number under the next bar to the right of the remainder. Add the last digit of the quotient to the divisor (9 + 9 = 18). Find a suitable number for the new divisor (180) for the new dividend (100).
Step 4: The new number in the quotient will be the same as selected in the divisor (180 × 0 = 0). It should be either less or equal to that of the dividend (180 > 100).
Step 5: Continue this process further using a decimal point and adding zeros in pairs to the remainder.
Step 6: The quotient obtained will be the square root of the number.

## 82 is Perfect Square root or Not
