Zad. 7
[tex]3^{6}:3^{9}=3^{6-9}=3^{-3}=\frac{1}{3^{3}}\\\\3^{6}*3^{9}=3^{6+9}=3^{15}\\\\3^{9}:3^{6}=3^{9-6}=3^{3}\\\\\boxed{Odp: 3^{6}:3^{9}=\frac{1}{3^{3}},3^{6}*3^{9}=3^{15},3^{9}:3^{6}=3^{3}}[/tex]
Zad. 8
[tex]3+3+3+3+3+3+3+3+3=9*3=3^{2}*3=\boxed{3^{3}}[/tex]
Zad. 9
[tex]2^{22}=2^{20+2}=2^{20}*2^{2}=1048576*4=\boxed{4194304}\\\\2^{19}=2^{20-1}=\frac{2^{20}}{2^{1}}=\frac{1048576}{2}=\boxed{524288}[/tex]
