Cześć!
Odpowiedź:
Szczegółowe wyjaśnienie:
a) [tex](\frac{4}{5} )^{2} =\frac{4\cdot4}{5\cdot5} =\frac{16}{25}[/tex]
b) [tex]-(1,5)^{2} =-(\frac{3}{2} )^{2} =-\frac{9}{4}[/tex]
c) [tex](-\frac{3}{2} )^{4} =\frac{3^{4} }{2^{4} } =\frac{81}{16}[/tex]
d) [tex](-2,2)^{2} =(-\frac{11}{5})^{2} =\frac{121}{25}[/tex]
e) [tex](1\frac{2}{5} )^{2} =(\frac{7}{5} )^{2} =\frac{49}{25}[/tex]
f) [tex]-(-\frac{2}{3} )^{3} =-(-\frac{8}{27} )=\frac{8}{27}[/tex]
g) [tex](-2\frac{2}{3} )^{3} =(-\frac{8}{3})^{3} =-\frac{512}{27}[/tex]
