Solve for a

$$\left\{\begin{matrix}\\a=0\text{, }&\text{unconditionally}\\a\in \mathrm{R}\text{, }&n_{30}=0\text{ or }l=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Anything times zero gives zero.

$$lan_{30}=\frac{0}{\sqrt{13}}$$

Rationalize the denominator of \frac{0}{\sqrt{13}} by multiplying numerator and denominator by \sqrt{13}.

$$lan_{30}=\frac{0\sqrt{13}}{\left(\sqrt{13}\right)^{2}}$$

The square of \sqrt{13} is 13.

$$lan_{30}=\frac{0\sqrt{13}}{13}$$

Anything times zero gives zero.

$$lan_{30}=\frac{0}{13}$$

Zero divided by any non-zero number gives zero.

$$lan_{30}=0$$

The equation is in standard form.

$$ln_{30}a=0$$

Divide 0 by ln_{30}.

$$a=0$$

Solve for C

$$C\in \mathrm{R}$$

$$n_{30}=0\text{ or }a=0\text{ or }l=0$$
