Since 13 is not a square number there is no exact real answer, but you can find an approximate value using the following (Newton-Raphson) iteration formula: xn+1=x n - (x2n -13)/(2xn). Using this formula the square root of 13 can be stated as 3.605551275 to 10 s.f. after 3 iterations starting from 3.5.
In mathematics, a square root of a number a is a number y such that y2 = a, in other words, a number y whose square (the result of multiplying the number by itself, or y Ã y) is a. For example, 4 and â4 are square roots of 16 because 42 = (â4)2 = 16.
