Square Root Questions

It has been often said that “practice makes perfect.” This phrase is actually very relatable when it comes to math as students can be good at the subject only by practicing and solving problems more and more. While it may not be easy but developing math skills and fluency is important. Mathematical skills of investigation, problem solving, and logical thinking can further help students progress in other subjects as well.

That being said, here in this page we will be discussing about the topic of square roots. Well, generally when we define the term, the square root of a number is a value that, when multiplied by itself, gives the number. For example, let’s say when you multiply 4 × 4 you get 16. So the square root of 16 is 4. This is the basic concept.

It is denoted by the symbol √ and it means that is a positive or perfect square root. For example, √36 = 6 (6 x 6 = 36). There are also square negative numbers. For example, (-5) X (-5) = 25. When we square a negative number we get a positive result.

Moving on, if you want to know how to find the square root of a number, then there are a lot of methods. However, the most basic method that can be used is the prime factorization method or the popular square root long division method. You can use this method to find the square root of a number that is satisfactory or accurate enough for you. An example of division method showing how to take the square root is given below;
