Answer:
The value of
is given by
. Hence, the answer is A.
Explanation:
This exercise represents a case where the Newton-Raphson method is used, whose formula is used for differentiable function of the form
. The expression is now described:

Where:
- Current approximation.
- New approximation.
- Function evaluated in current approximation.
- First derivative of the function evaluated in current approximation.
If
, then
. Now, given that
, the function and first derivative evaluated in
are:









The value of
is given by
. Hence, the answer is A.
