3. a) [tex](\frac{1}{3} )[/tex]⁰⁺¹⁺²⁺³= [tex](\frac{1}{3} )[/tex]⁶ se copie fractia si se aduna puterile
b) [tex](\frac{2}{5} )[/tex]⁶
c) [tex](\frac{2}{3} ) ^{0}[/tex]* [tex](\frac{2}{3} )^{3}[/tex] * [tex](\frac{2}{3} )^{2}[/tex] * [tex](\frac{2}{3} )^{5}[/tex] = [tex](\frac{2}{3} )^{10}[/tex]
d) [tex](\frac{1}{5} )^{2}[/tex]* [tex](\frac{1}{5} )^{0}[/tex] * [tex](\frac{1}{5^{2} } )^{0}[/tex]* [tex](\frac{1}{5^{4} } )[/tex]= [tex](\frac{1}{5^{2} } )[/tex]* 1 * 1 * [tex](\frac{1}{5^{4} } )[/tex]= [tex](\frac{1^{6} }{5^{6} } )[/tex]= [tex](\frac{1}{5 } )^{6}[/tex]
