Question

what methos can we use to find the cube of 7​

Answer 1

Answer:

All cube roots can be approximated by Newton-Raphson's method. To get the real cube root of any nonzero real number n, first guess a rough value for it(you may take it as 2 for the cube root of 7, since the cube of 2 is 8) and use the above method to find a root of the equation: f(x)=x^3 - m=0.
