what is root value in math In mathematics a square root of a number x is a number y such that in other words a number y whose square the result of multiplying the number by itself or is x For example 4 and 4 are square roots of 16 because
There is a fun method for calculating a square root that gets more and more accurate each time around a start with a guess let s guess 4 is the square root of 10 b divide by the guess 10 4 2 5 Square roots mean you multiply the same number twice to equal another number For example if you have the number 81 then the square root is 9 because 9 9 is 81 or 81 divided by 9 is 9

A square root of a number is a value that when multiplied by itself gives the number Example 4 4 16 so a square root of 16 is 4 Note that 4 4 16 too so 4 is also a square root of 16 A square root of x is a number r whose square is x r 2 x And we just found that 5 2 25 5 2 25 There are two numbers whose square makes 25 So both 5 and 5 are square roots of 25
First guess a convenient value for the square root Divide the number by your guess Now you have two numbers that multiply to get your original number Take the average of these two numbers This becomes your second guess for the square root Roots of polynomials Solving polynomials involves setting the polynomial equal to 0 and finding the value s for which the polynomial is equal to 0 These values or the solutions are called roots
