Radical Form: √1764

Is the Square Root of 1764 Rational or Irrational?

The square root of 1764 is an Rational Number.

The square root of 1764, which is 42, is a rational number. A rational number is one that can be expressed as a fraction of two integers, and since 42 can be represented as 42/1, it fits this definition. Unlike irrational numbers, rational numbers terminate or repeat in decimal form, making them distinct within the realm of mathematics.

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 1764

There are several methods to find the square root of 1764:

  1. Prime Factorization Method: Express 1764 as a product of its prime factors (2² × 3² × 7²) and then take the square root of each prime factor. The result is 2 × 3 × 7 = 42.
  2. Estimation Method: Approximate the square root of 1764 by considering perfect squares near it. Since 42² = 1764, the square root of 1764 is 42.
  3. Long Division Method: Use long division to find the square root iteratively. Start by guessing a number (e.g., 40) and then refine the guess through division and averaging until reaching the accurate value.
  4. Calculator: Utilize a calculator with a square root function to directly find the square root of 1764. Simply input 1764 and find its square root, which is 42.

Square Root of 1764 by Long Division Method


Forming Pairs: 17 and 64 We start by forming pairs from the number 1764. The pairs formed are 17 and 64.

Finding the Initial Digit Y (4) To find the initial digit Y such that its square is less than or equal to 17, we determine that Y = 4.

Initial Division: 17 divided by Y (4) We divide 17 by 4, which gives us a quotient of 4.

New Dividend: 164 After dividing, we bring down the next pair, 64, to the right of the remainder 1, forming the new dividend 164.

Finding Digit Z (2) To find the next digit Z such that the product of (8Z) and Z is less than or equal to 164, we determine that Z = 2.

New Divisor: 82 We combine the last digit of the quotient (4) with the newly found digit Z (2) to form the new divisor 82.

Further Division: 164 divided by 82 We divide 164 by the new divisor 82, resulting in a quotient of 2 and a remainder of 0.

Stopping the Process Since the remainder is now 0 and there are no more digits to bring down, we conclude the long division process.

Final Result: Square Root of 1764 Thus, the square root of 1764, found by the long division method, is 42.
