zad.2 [latex]x=0,(3)= frac{1}{3} [/latex] [latex]y=1,(3)=1 frac{1}{3}= frac{4}{3} [/latex] a). [latex] frac{1}{x}+ frac{1}{y}=3+ frac{3}{4}=3 frac{3}{4} [/latex] b). [latex] frac{1}{x ^{2} } + frac{1}{y ^{2} } =9+ frac{9}{16}=9 frac{9}{16} [/latex] c). [latex] frac{1}{x}+y ^{2} =3+ frac{16}{9}=4 frac{7}{9} [/latex] d). [latex] x^{2} - frac{1}{y ^{2} } = frac{1}{9}- frac{9}{16}= frac{16}{144}- frac{81}{144}=- frac{65}{144} [/latex] zad.4 a). [latex]a= sqrt{3} ^{3}=3 sqrt{3} [/latex] b). [latex]a=( frac{ sqrt{5} }{2}) ^{3} = frac{5 sqrt{5} }{8} [/latex] c). [latex]a=( sqrt{1 frac{1}{3} } ) ^{4} =( frac{4}{3}) ^{2}= frac{16}{9} [/latex] d). [latex]a=( frac{ sqrt{2} }{2} ) ^{4}= frac{4}{16} = frac{1}{4} [/latex] e). [latex]a=(2 sqrt{3}) ^{4} =16*9=144[/latex] f). [latex]a=(3 sqrt{2}) ^{4} =81*4=324[/latex]
