Вычислите:
а) $(2\frac{1}{5})^2$;
б) $(-3\frac{1}{3})^3$;
в) $(-1\frac{2}{3})^4$;
г) $(5\frac{1}{4})^2$.
$(2\frac{1}{5})^2 = (\frac{11}{5})^2 = \frac{121}{25} = 4\frac{21}{25}$
$(-3\frac{1}{3})^3 = (-\frac{10}{3})^3 = -\frac{1000}{27} = -37\frac{1}{27}$
$(-1\frac{2}{3})^4 = (-\frac{5}{3})^4 = \frac{625}{81} = 7\frac{58}{81}$
$(5\frac{1}{4})^2 = (\frac{21}{4})^2 = \frac{441}{16} = 27\frac{9}{16}$
