Odpowiedź:
a
[tex]\sqrt[3]{-\frac{8}{729} }[/tex] = [tex]-\frac{2}{9}[/tex]
b
[tex]\sqrt[3]{-0,000125}[/tex] = - 0,05
c
[tex]\sqrt[3]{-3\frac{3}{8} } =\sqrt[3]{-\frac{27}{8} } = -\frac{3}{2}= -1\frac{1}{2}[/tex]
Szczegółowe wyjaśnienie:
[tex](-\frac{2}{9}) *(-\frac{2}{9} )*(-\frac{2}{9} )=\frac{4}{81} *(-\frac{2}{9} )=-\frac{8}{729}[/tex]
(-0,05)*(-0,05)*(-0,05)=0,0025*(-0,05)= -0,000125
[tex](-\frac{3}{2} )*(-\frac{3}{2})*(-\frac{3}{2} )=\frac{9}{4} *(-\frac{3}{2} )=-\frac{27}{8} =-3\frac{3}{8}[/tex]
