"Root ka value" can mean a few different things depending on the context. 1. Square Root Value: If you mean the value of a square root, it's the number that, when multiplied by itself, gives the original number. For example, the square root of 9, written as √(9), is 3 because 3 × 3 = 9. The square root of 25, written as √(25), is 5 because 5 × 5 = 25. 2. Roots of an Equation: If you are talking about the roots of an equation (like a polynomial equation), these are the values of the variable that make the equation true. For example, in the equation x - 5 = 0, the root is x = 5 because when you substitute 5 for x, the equation becomes 5 - 5 = 0, which is true. For a quadratic equation like ax² + bx + c = 0, the roots are given by the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a) The "value" of the root depends on the specific values of a, b, and c. Please specify what kind of "root" you are asking about so I can give you a precise answer.
