Cześć!
Szczegółowe wyjaśnienie:
a)
[tex](1 \frac{1}{4} ) {}^{3} = ( \frac{5}{4} ) {}^{3} = \frac{5}{4} \cdot \frac{5}{4} \cdot \frac{5}{4} = \frac{125}{64} [/tex]
b)
[tex](2 \frac{2}{3} ) {}^{2} = ( \frac{8}{3} ) {}^{2} = \frac{8}{3} \cdot \: \frac{8}{3} = \frac {64}{9} [/tex]
c)
[tex]( - 1 \frac{1}{2} ) {}^{3} = ( - \frac{3}{2} ) {}^{3} = ( - \frac{3}{2} )\cdot( - \frac{3}{2} ) \cdot( - \frac{3}{2} ) = - \frac{ 27}{8} [/tex]
d)
[tex]( - 2 \frac{2}{5} ) {}^{2} = ( - \frac{12}{5} ) {}^{2} = - \frac{12}{5} \cdot - \frac{12}{5} = \frac{144}{25} [/tex]
