The values of various roots can be approximated using Newton's method.
For example, to approximate the value of √/10, let x =√10 and cube both sides
of the equation to obtain x³ = 10, or x³ - 10 = 0. Therefore, 10 is a root of
p(x)= x³ - 10, which can be approximated by applying Newton's method.
Approximate the following value of r by first finding a polynomial with integer
coefficients that has a root r. Use an app priate value of xo and stop calculating
approximations when two successive approximations agree to five digits to the
right of the decimal point after rounding.
