Is the Square Root of 1225 Rational or Irrational?

The square root of 1225 is rational number


The square root of 1225 is rational. A rational number is defined as a number that can be expressed as the fraction 𝑝𝑞​, where 𝑝 and 𝑞 are integers, and 𝑞 is not zero. The square root of 1225 is 35, which can be expressed as 35/1​. It fits perfectly into the category of rational numbers because it results in an integer without any need for an infinite or non-repeating decimal.


In contrast, a number is considered irrational if it cannot be expressed as a simple fraction where both the numerator and the denominator are integers, with the denominator not being zero. Irrational numbers have non-repeating, non-terminating decimal expansions. However, since the square root of 1225 is 35, a whole number, it is not irrational.

Methods to Find the Value of Root 1225

Finding the square root of 1225 can be done using several methods, each offering a clear pathway to understanding and determining the value. Here are a few commonly used methods:

1. Prime Factorization

  • Begin by factorizing 1225 into its prime factors. Since 1225=5²×7², the square root can be found by taking the root of each prime factor:
  • 1225=5²×7²=5×7=35.

2. Using a Calculator

  • The simplest and quickest method; just type 1225 into a calculator and press the square root function to get the exact value of 35.

3. Estimation

  • If you do not have access to a calculator, you can estimate the square root by finding numbers you know the squares of that are near 1225. For example, you know 30²=900 and 40²=1600. Since 1225 is closer to 900, you start estimating around 30 and find that 35²=1225.

4. Using Exponent Rules

  • Recognize that 1225 can be expressed as 35². This straightforward observation leads directly to the square root:
  • 1225=352²=35.

Square Root of 1225 by Long Division Method

To find the square root of 1225 using the long division method, you’ll follow a step-by-step process that breaks down the number systematically. Here’s how to do it:

  1. Set up the number: Arrange the digits of 1225 in pairs from right to left. For 1225, this will be 12 | 25.
  2. Find the largest square less than or equal to the first pair (12): The largest perfect square less than 12 is 9 (3²), so write 3 as the first digit of the quotient above the pair.
  3. Subtract the square from the first pair and bring down the next pair: Subtract 9 from 12 to get a remainder of 3. Bring down the next pair, making it 325.
  4. Double the quotient: Double the current quotient (which is 3), making it 6. This number will be the beginning of your next divisor.
  5. Find the next digit of the quotient: Look for a digit 𝑋 to place next to 6 in the quotient (making it 6X) and as the last digit in the divisor (60X + X), such that (60𝑋+𝑋)×𝑋≤325. 𝑋 will be 5 because 65×5=325.
  6. Complete the calculation: Subtract 325 from 325 to get a remainder of 0. Your quotient, which is now 35, is the square root of 1225.
