MCQ (Single Correct Answer)

-0.3

The iteration step in order to solve for the cube roots of a given number $$'N'$$ using the Newton-Raphson's method is

$${x_{k + 1}} = {x_k} + {1 \over 3}\left( {N - x_k^3} \right)$$

$${x_{k + 1}} = {1 \over 3}\left( {2{x_k} + {N \over {x_k^2}}} \right)$$

$${x_{k + 1}} = {x_k} - {1 \over 3}\left( {N - x_k^3} \right)$$

$${x_{k + 1}} = {1 \over 3}\left( {2{x_k} - {N \over {x_k^2}}} \right)$$
