Rozwiązanie:
[tex](2 \frac{1}{2})^4 = (\frac{5}{2})^4 = \frac{625}{16} = \boxed{39 \frac{1}{16}}[/tex]
[tex](2\frac{1}{2})^{4} = (\frac{2\cdot2 + 1}{2})^{4} = (\frac{5}{4})^{4}=\frac{5^{4}}{2^{4}} = \frac{625}{16} =39\frac{1}{16}\\\\\\Lub\\\\(2\frac{1}{2})^{4} = 2,5^{4} =2,5\cdot2,5\cdot2,5\cdot2,5 = 39,0625[/tex]
