1.7 Lösning 2c

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

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

\( \; \Downarrow \)

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

\( \; \Downarrow \)
