Introduction to Square Root of 288


The square root of 288 is a number which, when multiplied by itself, gives the product 288. In mathematical notation, it is represented as √288. Understanding how to simplify and calculate the square root of 288 can help in various mathematical and practical applications.


To simplify √288, we first find its prime factors. The prime factorization of 288 is 2^5 × 3^2. We can pair the factors to simplify the square root:

  • 288 = 2^5 × 3^2
  • √288 = √(2^5 × 3^2) = √(2^4 × 2 × 3^2) = √(2^4) × √(3^2) × √2 = 4 × 3 × √2 = 12√2


Thus, the simplified form of √288 is 12√2.


The square root of 288 can also be expressed in decimal form. Using a calculator, we find that √288 ≈ 16.9706. This decimal representation is useful for practical calculations and approximations.


When considering whether 288 is a perfect square, we observe that it is not, as its square root is not an integer. Consequently, √288 is an irrational number, meaning it cannot be expressed as a simple fraction.


There are multiple methods to calculate the square root of 288, including using a calculator, computer software, or the long division method. Each method offers a way to understand and work with square roots in different contexts.

Definition and Properties

The square root of a number \( n \) is a value that, when multiplied by itself, equals \( n \). In mathematical notation, the square root of 288 is written as \( \sqrt{288} \). The result is approximately 16.97.

Here are some important properties of the square root of 288:

  • Radical Form: \( \sqrt{288} = 12\sqrt{2} \). This is the simplified form of the square root of 288.
  • Decimal Form: The square root of 288 in decimal form is approximately 16.97.
  • Irrational Number: Since 288 is not a perfect square, \( \sqrt{288} \) is an irrational number. This means it cannot be expressed as a simple fraction and its decimal representation is non-terminating and non-repeating.
  • Exponent Form: The square root of 288 can also be written with an exponent: \( 288^{1/2} \).

The value 288 is not a perfect square because no integer squared will result in 288. Therefore, \( \sqrt{288} \) is always an irrational number.

Is 288 a Perfect Square?

No, 288 is not a perfect square. A perfect square is an integer that can be expressed as the product of an integer multiplied by itself. For example, 16 is a perfect square because it can be written as \(4^2\).

To determine if 288 is a perfect square, we need to see if there exists an integer which, when squared, equals 288. Let's break down the factors of 288:

  • Prime factorization of 288: \(288 = 2^5 \times 3^2\)

For a number to be a perfect square, all the exponents in its prime factorization must be even. In the case of 288, the exponents are 5 (odd) for the prime number 2, and 2 (even) for the prime number 3. Since not all exponents are even, 288 is not a perfect square.

The square root of 288 is approximately 16.97, which is not an integer. This further confirms that 288 is not a perfect square.

Rational or Irrational Number?

The square root of 288 can be determined to be either a rational or an irrational number. A rational number can be expressed as a fraction of two integers, whereas an irrational number cannot. To find out whether the square root of 288 is rational or irrational, we first need to check if 288 is a perfect square.

  • If 288 were a perfect square, then its square root would be a whole number, making it rational.
  • If 288 is not a perfect square, then its square root will be an irrational number.

Since 288 is not a perfect square (as there is no whole number which, when squared, equals 288), the square root of 288 is an irrational number. This means that it cannot be precisely expressed as a simple fraction.

Thus, we can conclude that \( \sqrt{288} \) is irrational.

  3. Identify the perfect squares from these groups:
    • (2 × 2) = 4
    • (2 × 2) = 4
    • (3 × 3) = 9
  4. Simplify the square root by pulling out the perfect squares:
    • √288 = √(4 × 4 × 9 × 2)
    • √288 = √(16 × 9 × 2)
    • √288 = √(144 × 2)
