[tex]8 = {2}^{3} \\ {8}^{11} = ( {2}^{3}) {?}^{11}[/tex]
(daca nu puneam ? nu ma lasa sa scriu, dar tu nu l baga in seama)
[tex] {8}^{11} = {2}^{3 \times 11} \\ {8}^{11} = {2}^{33} [/tex]
[tex]4 = {2}^{2} \\ {4}^{11} = ( {2}^{2}) {?}^{11} \\ {4}^{11} = {2}^{11 \times 2} \\ {4}^{11} = {2}^{22} [/tex]
[tex] {8}^{11} - {4}^{11} = \\ {2}^{33} - {2}^{22} = \\ [/tex]
