Вычислите степень:
а) $(\frac{1}{7})^2$;
б) $(\frac{3}{5})^2$;
в) $(\frac{1}{10})^3$;
г) $(\frac{2}{5})^3$;
д) $(1\frac{1}{3})^2$;
е) $(1\frac{1}{2})^3$.
$(\frac{1}{7})^2 = \frac{1}{7} * \frac{1}{7} = \frac{1}{49}$
$(\frac{3}{5})^2 = \frac{3}{5} * \frac{3}{5} = \frac{9}{25}$
$(\frac{1}{10})^3 = \frac{1}{10} * \frac{1}{10} * \frac{1}{10} = \frac{1}{1000}$
$(\frac{2}{5})^3 = \frac{2}{5} * \frac{2}{5} * \frac{2}{5} = \frac{8}{125}$
$(1\frac{1}{3})^2 = (\frac{4}{3})^2 = \frac{4}{3} * \frac{4}{3} = \frac{16}{9} = 1\frac{7}{9}$
$(1\frac{1}{2})^3 = (\frac{3}{2})^3 = \frac{3}{2} * \frac{3}{2} * \frac{3}{2} = \frac{27}{8} = 3\frac{3}{8}$
