Bisection Method - Help !!!!
It is required to find cubic root of 2 [(2)^1/3] to five decimal places, by solving the eqn
x^32=0
by means of the method of bisection. Estimate the number of iterations that will be required, and show this is so by performing the iterations.

\displaystyle \begin{align*} n \geq \frac{\ln{\left( \frac{b-a}{\epsilon} \right)}}{\ln{2}} \end{align*}
