Вычислите:
а) $(\frac{3}{4})^2 * 1\frac{1}{3}$;
б) $3^4 * (-\frac{2}{3})^3$;
в) $1 : (-\frac{1}{3})^3$;
г) $(\frac{3}{5})^2 * 1\frac{2}{3}$.
$(\frac{3}{4})^2 * 1\frac{1}{3} = \frac{9}{16} * \frac{4}{3} = \frac{3}{4} * \frac{1}{1} = \frac{3}{4}$
$3^4 * (-\frac{2}{3})^3 = 81 * (-\frac{8}{27}) = 3 * (-8) = -24$
$1 : (-\frac{1}{3})^3 = 1 : (-\frac{1}{27}) = -27$
$(\frac{3}{5})^2 * 1\frac{2}{3} = \frac{9}{25} * \frac{5}{3} = \frac{3}{5} * \frac{1}{1} = \frac{3}{5}$
