This means it cannot be expressed as a simple fraction, and its decimal representation is non-repeating and non-terminating.

A rational number can be expressed as the quotient of two integers, where the denominator is not zero.

An irrational number cannot be expressed as a fraction of two integers, and its decimal representation is non-repeating and non-terminating.

Methods to Find Value of Root 51

1. Prime Factorization Method

  • Express 51 as a product of its prime factors.
  • Simplify the expression by pairing the factors, then find the square root.

2. Long Division Method

  • Use long division to approximate the square root of 51.

3. Using a Calculator

  • Input √51 into a scientific calculator to obtain an approximation of the square root.

4. Newton’s Method (Iterative)

  • Start with an initial guess for the square root and use iterative formulae to refine the approximation.

5. Using a Table of Squares

  • Refer to mathematical tables listing square roots of numbers and find the closest approximation for √51.

Square Root of 51 by Long Division Method

Step 1: Begin by grouping the digits of 51 in pairs, starting from the right, and include any decimals.

Step 2: Identify a number whose square is less than or equal to 51, like 7.

Step 3: Divide 51 by 7, resulting in a quotient of 7 and a remainder of 2.

Step 4: Bring down the next pair of digits (in this case, zeros) to the remainder to form the new dividend, 200.

Step 5: Double the divisor and append a variable, resulting in a new divisor. Determine the value of the variable that makes the product of the divisor and the variable less than or equal to the new dividend.

Step 6: Place the determined value in the quotient after the decimal point, and continue the process with the updated divisor.

Is 51 Perfect Square root or Not

No, 51 is not a perfect square.

A perfect square is a number that can be expressed as the product of an integer with itself. Since there is no integer (n) such that (n× n = 51), 51 is not a perfect square.


Which value is closest to √51?

The two perfect squares surrounding 51 are (7² = 49) and (8² = 64). Since 51 lies closer to 49 than 64, the value closest to √51 is (7).

What is 51 cubed root?

The cube root of 51 is approximately equal to 3.707. This represents the number that, when multiplied by itself twice, equals 51.
