You asked:

Evaluate the expression: \(\frac{{12}^{1}}{3} \cdot \frac{{81}^{-1}}{6} \cdot \frac{{162}^{1}}{3}\)

MathBot Answer:

\[\frac{{12}^{1}}{3} \cdot \frac{{81}^{-1}}{6} \cdot \frac{{162}^{1}}{3} = \frac{4}{9} = 0.\overline{4}\]


\[\begin{aligned}\frac{{12}^{1}}{3} \cdot \frac{{81}^{-1}}{6} \cdot \frac{{162}^{1}}{3}& = 12^{1} \cdot \frac{1}{3} \cdot \frac{1}{81} \cdot \frac{1}{6} \cdot 162^{1} \cdot \frac{1}{3}\\& = \frac{12}{3} \cdot \frac{1}{81} \cdot \frac{1}{6} \cdot 162^{1} \cdot \frac{1}{3}\\& = \frac{12}{3} \cdot \frac{1}{81} \cdot \frac{162}{6} \cdot \frac{1}{3}\\& = \frac{12}{3} \cdot \frac{1}{81} \cdot \frac{54}{6}\\& = \frac{4}{81} \cdot \frac{54}{6}\\& = \frac{2}{243} \cdot 54\\& = \frac{4}{9}\end{aligned}\]
