Odpowiedź:
[tex]a) 1^{2} +1^{2} =a^{2} \\\\a^{2}=2\\a=\sqrt{2}[/tex]
[tex]a)=\sqrt{2}[/tex]
[tex]b)\sqrt{2} ^{2}+\sqrt{2} ^{2}=b^{2} \\b^{2} =4\\b=2[/tex]
[tex]b) =2[/tex]
[tex]c)2^{2} +2^{2}=c^{2}\\c^{2} =4+4\\c^{2} =8\\c=\sqrt{8}[/tex]
[tex]c)=\sqrt{8}[/tex]
[tex]d)\sqrt{8}^{2} +\sqrt{8}^{2} =d^{2} \\d^{2}=16\\d=4[/tex]
