Oblicz.
a)
[tex]( \frac{1}{5} ) {}^{2} = \frac{1}{5} = [/tex]
b)
[tex]( \frac{2}{5} ) {}^{3} = [/tex]
c)
[tex](1 \ \frac{2}{5} ) {}^{2} = [/tex]
d)
[tex](2 \frac{1}{2} ) {}^{3} = [/tex]

Odpowiedź:

$(\frac{1}{5})^{2} = \frac{1}{5}*\frac{1}{5} = \frac{1}{25}$

$(\frac{2}{5})^{3} = \frac{2}{5} *\frac{2}{5} *\frac{2}{5} = \frac{8}{125}$

$(1\frac{2}{5})^{2} = \frac{7}{5}*\frac{7}{5}=\frac{49}{25}=1\frac{24}{25}$

$(2\frac{1}{2})^{3} = \frac{5}{2}*\frac{5}{2}*\frac{5}{2}=\frac{125}{8}= 15\frac{5}{8}$

$a) \: {\left( \frac{ 1 }{5} \right) }^{2} = \frac{1}{5} \times \frac{1}{5} = \frac{1}{25} \\ b) \: {\left( \frac{2}{5} \right) }^{3} = \frac{2}{5} \times \frac{2}{5} \times \frac{2}{5} = \frac{8}{125} \\ c) \: { \left( 1\frac{2}{5} \right)}^{2} = { \left( \frac{7}{5} \right)}^{2} = \frac{7}{5} \times \frac{7}{5} = \frac{49}{25} = 1 \frac{24}{25} \\ d) \: { \left(2 \frac{1}{2} \right)}^{3} = { \left( \frac{5}{2} \right)}^{3} = \frac{5}{2} \times \frac{5}{2} \times \frac{5}{2} = \frac{125}{8} = 15\frac{5}{8}$
