## Is the Square Root of 47 Rational or Irrational?

The square root of 47 is irrational.

This is because 47 is not a perfect square, and its square root cannot be expressed as a simple fraction of two integers.

An irrational number, such as √2 or π, cannot be expressed as a fraction of two integers. Its decimal expansion neither ends nor repeats, thus it defies representation in the form a/b.

A rational number can be expressed as a fraction of two integers, denoted as a/b, where the denominator isn’t zero

## Method to Find Value of Root 47

To find the value of the square root of 47, you can use several methods. Here are two common approaches:

1. Long Division Method:

• Set up the number in pairs of digits starting from the decimal point: (47.000000) (consider as many decimal places as needed for precision).
• Find the largest integer whose square is less than or equal to 47: (6× 6 = 36). Write 6 as the quotient and 36 under 47, then subtract to get a remainder of 11.
• Bring down the next pair of zeros (to make 1100).
• Double the quotient (6) and write it as the new divisor’s leading digit: (12_ ).
• Find the largest digit (D) to fill in the blank such that (12D × D) is less than or equal to 1100: (124 × 4 = 496). Write 4 next to the 6 in the quotient.
• Subtract to find the new remainder: (1100 – 496 = 604).
• Repeat the process by bringing down pairs of zeros and finding the next digits.

2. Calculator Method:

• Enter 47 into a calculator.
• Press the square root (√) button.
• The calculator will display the square root of 47: approximately (6.855654600).

3. Approximation Method:

• Identify perfect squares close to 47: (36) (since (6² = 36)) and (49) (since (7² = 49)).
• Estimate the value: Since (47) is closer to (49) than (36), we know √47 is slightly less than (7).
• Refine the guess: Through trial and error or interpolation, you can get closer to the exact value.
• Using these methods, you can determine that the square root of 47 is approximately (6.855654600).

## Square Root of 47 by Long Division Method

Step 1: Starting from the right, pair up the digits of 47 by putting a bar above them. Also, pair the 0s in the decimals in pairs of 2 from left to right.

Step 2: Think of a number whose square is less than or equal to 47. In this case, that number would be 6.

Step 3: Dividing 47 by 6 with the quotient set as 6, we get a remainder of 11.

Step 4: Drag a pair of 0s down and place them next to 11 to make the dividend 1100.

Step 5: The divisor (6) is doubled and written below. Now, we have 12X as the new divisor, and we need to find a value of X that makes the product of 12X × X less than or equal to 1100. In this case, 128 is the required value.

Step 6: The new divisor for the next division will be 128 + 8 = 136. The number 5 is placed in the quotient after the decimal place. The new divisor for the next division is 1365.

Step 7: Proceeding in the same manner and repeating from step 4, we can calculate the rest of the decimals.

## 47 is Perfect Square root or Not?

47 is not a perfect square.

A perfect square is a number that can be expressed as the square of an integer. Since there is no integer that, when squared, equals 47, it is not a perfect square.

## What is 47 divisible by?

47 is divisible only by 1 and 47. This is because it has no other factors apart from 1 and itself.

## Is 47 a prime number?

Yes, 47 is a prime number. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Since 47 has no divisors other than 1 and 47 itself, it is classified as a prime number.

## Is 47 a real number?

Yes, 47 is a real number. In mathematics, real numbers include all rational and irrational numbers, and 47 falls under this category as it is a rational number.
