d) ([tex]\frac{6\sqrt{2} }{2} ^{2} = (3\sqrt{2}) ^{2} \\[/tex] = 9 * 2 = 18
e) [tex]\frac{6}{\sqrt{3} }[/tex] * [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex] = [tex]\frac{6\sqrt{3} }{3}[/tex] = [tex](2\sqrt{3}) ^{2}[/tex] = 4 * 3 = 12
f) [tex]\frac{3}{2\sqrt{6} }[/tex] * [tex]\frac{\sqrt{6} }{\sqrt{6} }[/tex] = [tex]\frac{3\sqrt{6} }{2*6}[/tex] = [tex]\frac{3\sqrt{6} }{12}[/tex]
mam nadzieje ze pomoze ;)
