4.284 Вычислите степень дробного числа: a) (-1/2)³; б) (-2/3)⁴; в) (-5/4)³; г) (-1 1/2)³; д) (-2 1/3)²; e) (-1 2/3)³

a) \((-1/2)^3 = (-1/2) * (-1/2) * (-1/2) = -1/8\) б) \((-2/3)^4 = (-2/3) * (-2/3) * (-2/3) * (-2/3) = 16/81\) в) \((-5/4)^3 = (-5/4) * (-5/4) * (-5/4) = -125/64 = -1 \frac{61}{64}\) г) \((-1 \frac{1}{2})^3 = (-3/2)^3 = (-3/2) * (-3/2) * (-3/2) = -27/8 = -3 \frac{3}{8}\) д) \((-2 \frac{1}{3})^2 = (-7/3)^2 = (-7/3) * (-7/3) = 49/9 = 5 \frac{4}{9}\) е) \((-1 \frac{2}{3})^3 = (-5/3)^3 = (-5/3) * (-5/3) * (-5/3) = -125/27 = -4 \frac{17}{27}\)
