    Struggling to derive a formula, cant say im confident in what I have derived, also how do you choose a suitable value to start of with.

    <br /> \begin{gathered}<br /> 2\ln 5x - 3 = 0 \hfill \\<br /> \Leftrightarrow x = \frac{{e^{\frac{3}<br /> {2}} }}<br /> {5} \hfill \\ <br /> \end{gathered} <br />
