## Is the Square Root of 2401 Rational or Irrational?

The square root of 2401 is rational number

## Rational

Yes, the square root of 2401 is rational. A rational number is defined as one that can be expressed as a fraction where both the numerator and the denominator are integers, and the denominator is not zero. The square root of 2401 is 49, which can clearly be expressed as the fraction 49/1​, making it a rational number.

### Irrational

No, the square root of 2401 is not irrational. Irrational numbers are those that cannot be expressed as a simple fraction; they have endless, non-repeating decimal parts. Since the square root of 2401 is 49, a precise integer, it does not fit the definition of an irrational number.

## Methods to Find the Value of Root 2401

Finding the square root of 2401 doesn’t necessarily require the long division method. Here are alternative methods to determine this value effectively:

## 1. Using a Calculator

The quickest and most straightforward method is to use a calculator. Most calculators have a square root function, and you simply need to enter 2401 and press the square root button to get the result, which is 49.

## 2. Prime Factorization

You can find the square root of 2401 through prime factorization. Start by breaking down 2401 into its prime factors. The factorization of 2401 is 7×7×7×7⁴. The square root of 7474 is 7272, which simplifies to 49.

## 3. Guess and Check Method

You can also find the square root by making educated guesses. Knowing that 2401 is a square number between 50² (2500) and 40² (1600), you can start guessing with numbers close to 50. Testing 49 shows that 49×49=240149×49=2401, thus revealing that the square root of 2401 is 49.

## 4. Square Root Spiral or Table

Another educational method involves using a square root spiral or a square root table. A square root spiral visually demonstrates squares and their roots, while a table lists numbers and their corresponding square roots. Simply look up 2401 in the table to find its square root.

## Square Root of 2401 by Long Division Method

Calculating the square root of 2401 using the long division method is a systematic process that involves several steps. This method is similar to the traditional division but tailored specifically for finding square roots. Here is a step-by-step guide on how to use the long division method to find the square root of 2401:

1. Set up the number:
• Write 2401 and start by grouping the digits from right to left into pairs. In this case, we have two groups: 24 and 01.
2. Find the largest square less than or equal to the first group:
• The first group is 24. The largest perfect square less than or equal to 24 is 16, which is 4².
• Write 4 as the first digit of your result above the square root line.
3. Subtract and bring down the next group:
• Subtract 16 from 24, which leaves 8.
• Bring down the next group (01), making it 801.
4. Double the divisor and find the next digit:
• Double the current quotient (4), which gives you 8. Place this next to the remainder, forming 80.
• Find a digit 𝑑 that fits in 𝑑 (in 80𝑑≤801). In this case, d = 9 works because 809×9=7281 (too high), so use 809.
• Place 9 beside 4 in your quotient, making the new quotient 49.
5. Perform the subtraction and find the remainder:
• Multiply 809 by 9 to get 7281, and subtract from 8010 (after bringing down another pair of zeros if needed). However, as we see, 809 is too high.
• Adjusting it to 809 (80 with 9 as the digit) results in 809×9=7281, and use this to adjust. You’ll see that the perfect number would have been 809, so using 49 instead of 4, results in 49×49=2401.
• Subtract 2401 from 2401, leaving a remainder of 0.
6. Conclusion:
• Since there are no more digits to bring down and the remainder is 0, the process is complete.
