## Square Root of 144 by Prime Factorization Method

The prime factorization method to find the *square root of 144* involves breaking down the number 144 into its basic prime factors. Prime factorization means expressing a number as the product of its prime numbers, which are numbers greater than 1 that have no divisors other than 1 and themselves.

Hereās how to use the prime factorization method for 144:

**Divide the Number**: Start by dividing 144 by the smallest prime number that can evenly divide it, which is 2. Keep dividing the quotient by 2 until you cannot evenly divide by 2 anymore.- 144 Ć· 2 = 72
- 72 Ć· 2 = 36
- 36 Ć· 2 = 18
- 18 Ć· 2 = 9
- Now, 9 is not divisible by 2, so we switch to the next smallest prime number, which is 3.
- 9 Ć· 3 = 3
- 3 Ć· 3 = 1

**Write Down the Prime Factors**: The prime factors of 144, based on the divisions above, are 2ā“ and 3Ā².**Calculate the Square Root**: To find the square root, take the square root of each prime factor and multiply them. For each prime factor, divide the exponent by 2 and multiply the results.

Therefore, the square root of 144 by the prime factorization method is 12. This method is not only useful for finding square roots but also helps in understanding the fundamental structure of numbers, enhancing oneās ability to perform various mathematical calculations.

## Square Root of 144 by Long Division Method

The long division method is a systematic approach to finding the square root of a number, particularly useful when dealing with perfect squares like 144. Here’s how to apply this method to calculate the square root of 144 step-by-step:

**Step 1: Set Up the Number**

Arrange 144 for the division, and start by grouping the digits in pairs from the right. For 144, place a bar over the pair of digits from the right and the remaining single digit on the left. This means you put one bar over 44 and another bar over the 1.

**Step 2: Find the First Digit**

Identify a number which, when squared, gives a result equal to or less than the first group under the bar, here ‘1’. The highest square less than or equal to 1 is 1 (since 1Ā² = 1).

**Step 3: Bring Down the Next Pair**

Now, bring down the next pair of numbers next to the remainder. In this case, it is 44. The initial quotient is 1, so double this number (1 Ć 2 = 2) and write it down as the divisor’s tens place digit for the next step.

**Step 4: Find the Units Place**

Choose a digit for the units place of the divisor such that when the new divisor is multiplied by this digit, the product is closest to but not greater than the number you just brought down (44 in this case). Here, the correct digit is 2, making the new divisor 22 (since 22 Ć 2 = 44).

By following these steps, you determine that the square root of 144 by the long division method is 12. This method not only calculates square roots but also reinforces the understanding of basic multiplication and subtraction skills in a structured format.
