\( \, (4 \,/\, 2)\,^2 \, = \, (\,2\,)\,^2 \, = \, 2\,^2 \, = \, 2 \cdot 2 \, = \, 4 \, \)

\( \, 4\,^2 \,/\, 2\,^2 \, = \, 4 \cdot 4 \, \,/\, \, 2 \cdot 2 \, = \, 16 \,/\, 4 \, = \, 4 \, \)


\[ \;\;\, 4 \quad = \quad 4 \, \]
\( \; \Downarrow \)
\[ \;\;\, (4 \,/\, 2)\,^2 \; = \; 4\,^2 \,/\, 2\,^2 \, \]
\( \; \Downarrow \)
