Is the Square Root of 35 Rational or Irrational?

A rational number is any number that can be expressed as a fraction a/b where a and b are integers, and b is not equal to zero. It includes integers, fractions, and finite or repeating decimals.

An irrational number is a number that cannot be expressed as a simple fraction. Irrational numbers have non-repeating, non-terminating decimal expansions.

This means it cannot be expressed as a fraction of two integers (no matter how large the numbers might be), and its decimal representation goes on infinitely without repeating. Therefore, the square root of 35 is irrational, as it cannot be expressed as a fraction in simplest form, similar to other irrational numbers such as the square root of 21.

Method to Find Value of Root 35

There are several methods to find the square root of 35:

1. Prime Factorization Method:

   • Express 35 as a product of its prime factors: 35 = 5 × 7.
   • Take one factor from each pair of the prime factors and multiply them: √(5 × 7) = √5 × √7.
   • Since 5 and 7 are both prime, their square roots are irrational, so the square root of 35 cannot be simplified further.

2. Estimation Method:

   • Start with an initial guess for the square root of 35, such as 6.
   • Square this guess: 6² = 36.
   • Since 36 is greater than 35, adjust the guess downwards.
   • Repeat this process until reaching a satisfactory approximation.

3. Long Division Method:

   • Use the long division method similar to polynomial division to calculate the square root of 35 to a desired level of precision.
   • This method involves repeatedly subtracting and bringing down digits to approximate the square root.

4. Iterative Methods:

   • Utilize iterative algorithms like Newton’s method or the Babylonian method to iteratively refine an initial guess for the square root of 35 until reaching a satisfactory approximation.

Square Root of 35 by Long Division Method

To find the square root of 35 using the long division method, follow these steps:

Set Up the Number: Place the number 35 under the square root sign.

Estimate the Integer Part: Estimate the largest integer whose square is less than or equal to 35. In this case, it’s 5, as 5² = 25.

Divide and Average: Divide 35 by 5, which gives 7. Add the quotient (5) and the divisor (5), then divide by 2 to get the average: (5 + 7) ÷ 2 = 6.

Repeat the Process: Use this average (6) as the next divisor. Divide 35 by 6, which gives approximately 5.833.

Refine the Average: Repeat the process, adjusting the divisor and finding the average until reaching the desired level of accuracy.

Finalize the Result: Continue the process until the decimals repeat or until the desired level of precision is achieved. The resulting quotient provides the decimal approximation of the square root of 35.

Following these steps, the square root of 35, obtained by the long division method, is approximately 5.916.
