Use Newton's method to obtain the third approximation, x,, of the positive fourth root of 8 by calculating the third approximation of the right 0 of f(x) =x* - 8. Start with x, = 1. The third approximation of the fourth root of 8 determined by calculating the third approximation of the right 0 of f(x) = x* - 8, starting with x, = 1, is (Round to four decimal places.)
