Answer 1

а) $(\frac{1}{2})^{2} =\frac{1^{2}}{2^{2}}=\frac{1}{4} = 0,25$

б) $(\frac{2}{5} )^{2}=\frac{2^{2}}{5^{2}} =\frac{4}{25} =\frac{16}{100} =0,16$

в) $(\frac{2}{3} )^{3} = \frac{2^{3}}{3^{3}}=\frac{8}{27}$

г) $(\frac{2}{5})^{3}=\frac{2^{3}}{5^{3}}=\frac{8}{125} =\frac{64}{1000}=0,064$

д) $(2\frac{1}{2})^{2}=(\frac{5}{2})^{2}=\frac{5^{2}}{2^{2}}=\frac{25}{4}=\frac{625}{100} =6,25$

е) $(3\frac{1}{3})^{3}=(\frac{10}{3})^{3}=\frac{10^{3}}{3^{3}} =\frac{1000}{27}$

ж) $(1\frac{1}{5})^{2}=(\frac{6}{5})^{2}=\frac{6^{2}}{5^{2}}=\frac{36}{25}=\frac{144}{100} =1,44$

з) $(1\frac{1}{4})^{2}=(\frac{5}{4})^{2}=\frac{5^{3}}{4^{3}} =\frac{125}{64} = 1\frac{61}{64}$
