Davneet Singh is a graduate from Indian Institute of Technology, Kanpur. \(1\) and \(80\) There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others. Hence, verify = product of two numbers. It can factor expressions with polynomials involving any number of vaiables as well as more complex functions. The square root is just a reverse application of square, it means when a number multiplied 2-times by itself then it will result in the square and the root number of this result is called square root. Thus, 729 = 3 × 3 × 3 × 3 × 3 × 3 Prime factorization and estimation methods can be used to find the cube roots of perfect cubes only. For each of the Following numbers, find the smallest whole number by which it should be multiplied so as to get a perfect square number.

Ex 6.3, 4 Find the square roots of the following numbers by the Prime Factorization Method. This is a step by step guide for finding the value of square root of 4096.For finding the square root of any number we have two methods. Since the number is a perfect square, you will be able to make an exact number of pairs of prime factors. In this method, we need to list the prime factors of the given number and then make the pair of two same numbers. We can also complete the square to find the vertex more easily, since the vertex form is \(y=a{{\left( {x-h} \right)}^{2}}+k\).
