Odpowiedź:
[tex]\frac{27^{5}*81 / (3^{-2})^{3} * 9^{-2} / (27^{-2})^{-1}}{9^{7} / (3^{5})^{2} * 81^{-2}} = \frac{(3^{3})^{5}*3^{4} / (3^{-2})^{3} * (3^{2})^{-2} / ((3^{3})^{-2})^{-1}}{(3^{2}^{7} / (3^{5})^{2} * (3^{4})^{-2}} = \frac{3^{15}*3^{4} / 3^{-6} * 3^{-6} / 3^{6}}{3^{14} / 3^{10} * 3^{-8}} =[/tex]
[tex]= \frac{3^{60} / 3^{36} / 3^{6}}{3^{14} / 3^{-80}} = \frac{3^{18}}{3^{-66}} = 3^{84}[/tex]
P.S. Może to błąd z podstawą "2".
