Step-by-step explanation:

$\sf \: \star\:ii.\:\star \\ \\ \sf \left[\begin{array}{cc}1&0\\-1&3\end{array} \right ] \\ \\ \sf {R}_{1} \longrightarrow {R}_{2} \\ \\ \sf = \left[\begin{array}{cc}-1&3\\1&0\end{array} \right ] \\ \\ \sf \star \: iii.\:\star \\ \\ \sf y = 1 + logx \\ \\ \sf Differentiating \: w.r.t. \: x \\ \\ \sf \frac{dy}{dx} = 0 + \frac{1}{x} \\ \\ \sf \frac{dy}{dx} = \frac{1}{x}$
