Szczegółowe wyjaśnienie:
[tex]( \frac{1}{2} + \frac{1}{4} )^{2} = { (\frac{1}{2} )}^{2} + 2( \frac{1}{2} \times \frac{1}{4} ) + {( \frac{1}{4} )}^{2} = \frac{1}{4} + \frac{1}{4} + \frac{1}{16} = \frac{4}{16} + \frac{4}{16} + \frac{1}{16} = \frac{9}{16} [/tex]
[tex] { (\frac{1}{2} )}^{2} + { (\frac{1}{4} )}^{2} = \frac{1}{4} + \frac{1}{16} = \frac{4}{16} + \frac{1}{16} = \frac{5}{16} [/tex]
[tex] \frac{9}{16} > \frac{5}{16} [/tex]
