Is the Square Root of 900 Rational or Irrational?

Yes, the square root of 900 is a rational number

The square root of 900 is rational. This is because 900 is a perfect square, being the product of a whole number (30) multiplied by itself. In general, the square root of any perfect square is a rational number.

A rational numbers is any number that can be expressed as a fraction of two integers, where the denominator is not zero. Since 18 can be expressed as 18/1, it fits this definition, making it a rational number.

Rational numbers are numbers that can be expressed as a quotient or fractions of two integers, where the denominator isn’t zero.

Examples : 1/2​, 3/4​, −5/7

Irrational numbers cannot be expressed as fractions and have non-repeating, non-terminating decimals.

Examples : π, √2​, and e.

Methods to Find Value of Root 900

There are several methods to find the value of the square root of 900:

Calculator: The easiest and most common method is to use a calculator. Simply input “√900” into a calculator, and it will give you the answer directly, which is 30.

Prime Factorization: You can break down 900 into its prime factors, which are (2², 3², 5²). Then, take one factor from each pair and multiply them together, giving you (2 \times 3 \times 5 = 30).

Long Division: This method involves dividing 900 by a number repeatedly until you get a quotient close to the divisor. This process requires some trial and error, but it’s a good exercise for understanding square roots. Start with a guess (e.g., 30), divide 900 by this guess, adjust your guess as needed, and continue until you find the square root.

Estimation: Since 900 is very close to the perfect square 961 (31²) you can estimate the square root to be close to 31. This gives you a ballpark figure to work with.

Square Root of 900 by Long Division Method


Finding the Square Root of 900:

First, we look for a number that, when multiplied by itself, equals a number that’s less than or equal to 900. This gives us a starting point to work with.

Long Division for Square Root:

We perform long division to find the square root of 900. We divide 900 by numbers starting from 1 until we find one that gives a quotient with no remainder.

Completion of Long Division:

When we find a number that evenly divides 900 without leaving a remainder, like 30, we stop the long division process. Since the remainder is 0, we’ve found our square root.

Considering Negative Square Root:

Now, can the square root of 900 be -30? We can find out by squaring -30. (-30²) equals 900, confirming that -30 is indeed a valid square root of 900. However, typically, we consider only the positive root unless specified otherwise.

Real or Imaginary Number:

Lastly, what about (√-900)? Well, in the realm of real numbers, there’s no number whose square is negative. So, (√-900) is not a real number. It belongs to the domain of complex numbers.

Is 900 Perfect Square root or Not

Yes, the number 900 is a perfect square

Yes, 900 is a perfect square because it is the square of a whole number. Specifically, (30² = 900), indicating that 900 is a perfect square.


Can the square root of 900 be -30?

Yes, because (−30)2=900(−30)2=900. However, the convention is to consider only the positive square root unless specified otherwise.

Is the square root of -900 a real number?

No, because in the realm of real numbers, there’s no number whose square is negative. The square root of -900 belongs to the domain of complex numbers.

How can I calculate the square root of 900?

You can calculate it using methods like prime factorization, long division, or simply by using a calculator.

What is a square number?

A square number is the result of multiplying a number by itself. In the case of 900, it is a square number because 30×30=900

What are some real-world applications of understanding square roots?

Understanding square roots is crucial in various fields such as engineering, physics, and finance. For example, in engineering, it’s used in calculating areas, volumes, and dimensions. In finance, it’s used in calculating interest rates and investment growth.
