Explicație pas cu pas:

8) $\frac{9^{41} - 3^{80} }{27^{27} } =$ $\frac{3^{2^{41} } - 3^{80} }{(3 * 9)^{27} }$ = $\frac{3^{82} - 3^{80} }{3^{27} * 9^{27} }$ = $\frac{3^{80} (3^{2} - 1) }{3^{27} * 3^{2^{27} } }$ = $\frac{3^{80} * 8 }{3^{27} * 3 ^{59} }$ = $\frac{3^{80} * 8 }{3^{86} }$ = $\frac{8 }{3^{6} }$
