Oplossing - Solution

\begin{aligned} & 0,1^{\frac{3}{x}} = 100^4 \\ \Leftrightarrow & \; {(10^{-1})^{\frac {3}{x}} = 10^8 } \\ \Leftrightarrow & \; 10^{\frac {-3}{x}} = 10^8 \\ \Leftrightarrow & \; \frac {-3}{x} = 8 \\ \Leftrightarrow & \; 8x =-3 \\ \Leftrightarrow & \; x=\frac{-3}{8} \\ \end{aligned}
