## Methods to Find Value of Root 324

Prime Factorization: Decompose 324 into its prime factors (2^2 * 3^4). Then, take half of the exponent of each prime factor (2 * 3^2), and multiply them together (2 * 9 = 18).
Estimation: Since 324 falls between the squares of 18 (324) and 19 (361), the square root is likely close to 18.
Long Division Method: By dividing 324 by successive perfect squares until the quotient stabilizes, you can approximate the square root.
Newton’s Method: Use iterative approximation starting with an initial guess (e.g., 15), then refine the guess using the formula:
𝑥ₙ₊₁ = 1/2(𝑥ₙ+324/𝑥ₙ) until convergence.

## Square Root of 324 by Long Division Method

Step 1: Write down 324. Pair the digits from right to left.

Step 2: Divide 8 by a number that, when squared, is less than or equal to 8. 2 works, giving us a quotient of 2 and a remainder of 4.

Step 3: Double the quotient to get 4, making our new divisor 40. Bring down the next digit, 1, making our new dividend 41. Find a number such that (40 + that number) times the number is less than or equal to 41. 9 works, giving us 441.

Step 4: Subtract 441 from 441, resulting in a remainder of 0, and a quotient of 18.

Step 5: Therefore, the square root of 324 is 18.

## Is 324 Perfect Square root or Not
