Product Information

To find the square root of any number, we need to figure out whether the given number is a perfect square or an imperfect square. If the number is a perfect square, such as 4, 9, 16, etc., then we can factorize the number by prime factorisation method. If the number is an imperfect square, such as 2, 3, 5, etc., then we have to use a long division method to find the root. As per the repeated subtraction method, if a number is a perfect square, then we can determine its square root by: The square root of any negative numbers is not defined because the perfect square cannot be negative.

Some common roots include the square root, where n = 2, and the cubed root, where n = 3. Calculating square roots and n th roots is fairly intensive. It requires estimation and trial and error. There exist more precise and efficient ways to calculate square roots, but below is a method that does not require a significant understanding of more complicated math concepts. To calculate √ a: For example, the square root of 4 is 2 and the square root of 9 is 3, thus, we can guess the square root of 5 will lie between 2 and 3.The square root symbol is usually denoted as ‘ √’. It is called a radical symbol. To represent a number ‘x’ as a square root using this symbol can be written as: A decimal value will have a dot (.) such as 3.8, 5.2, 6.33, etc. For a whole number, we have understood how to derive the square root but let us see how to get the square root of a decimal. Example: Find the square root of 0.09.Let N 2 = 0.09 where x is the number. The number under the radical symbol is called the radicand. For example, the square root of 6 is also represented as radical of 6. Both represent the same value. In mathematics, the general root, or the n th root of a number a is another number b that when multiplied by itself n times, equals a. In equation format: Below are the numbers which are perfect squares and then finding the square roots of such numbers is easy.

The two square root values can be multiplied. For example, √3 can be multiplied by √2, then the result should be √6. If a number ends with 2, 3, 7 or 8 (in the unit digit), then the perfect square root does not exist.
