Zadanie 8.
a) [tex]\frac{3^{5}*3^{7}*3^{0}}{3^{16}:(3^{2}) ^{3}} = \frac{3^{5+7+0} }{3^{16}: 3^{2*3}} = \frac{3^{12} }{3^{16}:3^{6}} = \frac{3^{12} }{3^{16-6}} = \frac{3^{12}}{3^{10}} = 3^{12-10}= 3^{2}= 9[/tex]
b) [tex]-18^{6} * (\frac{1}{9}) ^{6} = (-18*\frac{1}{9})^{6}=(\frac{-18}{9})^{6}= -2^{6} =64[/tex]
