A rational number is any number expressible as a fraction of two integers.
Examples : 3/4 or -5/2

An irrational number cannot be expressed as a fraction of two integers and its decimal expansion neither terminates nor repeats.
Examples : √2, which is approximately 1.41421356…, is irrational.

Methods to Find Value of Root 89

There are several methods to find the value of the square root of 89:

1. Prime Factorization Method: Express 89 as a product of prime factors (89 is a prime number, so it’s only divisible by 1 and 89), then group the factors into pairs. The square root of 89 is the product of the square roots of these pairs.
2. Estimation Method: Approximate the square root of 89 by finding perfect squares near it. Since 89 is between 81 (9²) and 100 (10²), its square root is between 9 and 10. Refine the estimate using methods like Newton’s method.
3. Long Division Method: Use the long division method to find the square root of 89 iteratively. This involves dividing 89 by a guess, averaging the result with the guess, and repeating until a satisfactory level of precision is achieved.
4. Calculator or Software: Use a calculator or mathematical software to directly compute the square root of 89. Most calculators and software packages have built-in functions for calculating square roots.
5. Continued Fraction Expansion: Express the square root of 89 as a continued fraction and approximate its value by truncating the expansion at a certain point.

Square Root of 89 by Long Division Method

The long division method stands as a common and reliable approach for finding square roots. It simplifies multi-digit numbers into manageable parts, aiding comprehension and accuracy.

To find the square root of 89 using long division:

Step 1: Write 89 within the division symbol.

Step 2: Divide 89 into pairs, resulting in just 89.

Step 3: Start dividing the number, aiming for a quotient that, when squared, is either equal to or less than 89. Here, the quotient is 8 with a remainder of 8.

Step 4: Bring down the next pair, making the dividend 800. Double the previous quotient (8) to get 16, which becomes the next divisor.

Step 5: Pair 16 with another digit to form a divisor that, when multiplied by itself, results in a number close to 800. If necessary, add pairs of zeros to the right before beginning division.

89 is Perfect Square root or Not

No, 89 is not a perfect square. A perfect square is a number that can be expressed as the product of an integer with itself. For example, 9 is a perfect square because it is equal to 3 × 3. However, 89 cannot be expressed as the product of two equal integers, so it is not a perfect square.
