5. a) [tex] 9^{0} +1^{8} +8^{1}-0^{2004}=1+1+8-0=10[/tex]
b) Sunt numere prea mari, probabil e gresita problema. (nu se simplifica puterile lui 2 acolo)
6. a) [tex]x^{0}=1[/tex], deci [tex]2003^{0} \ \textgreater \ 0^{2003}[/tex]
b) [tex]5^{300} = (5^{2)^{150[/tex]
c) [tex](3^{2})^{10} \ \textgreater \ (2^{2})^{10}[/tex] ⇔ [tex]3^{20} \ \textgreater \ 2^{20}[/tex]
