б) б³ при b = -2; b = -\frac{1}{5}; b = 0,1; b = -0,1; b = -1\frac{1}{2}; b = 2\frac{1}{2}.

б) Вычислим значение \(b^3\) для каждого значения b: 1) \(b = -2\), \(b^3 = (-2)^3 = -8\) 2) \(b = -\frac{1}{5}\), \(b^3 = (-\frac{1}{5})^3 = -\frac{1}{125}\) 3) \(b = 0,1\), \(b^3 = (0,1)^3 = 0,001\) 4) \(b = -0,1\), \(b^3 = (-0,1)^3 = -0,001\) 5) \(b = -1\frac{1}{2} = -\frac{3}{2}\), \(b^3 = (-\frac{3}{2})^3 = -\frac{27}{8}\) 6) \(b = 2\frac{1}{2} = \frac{5}{2}\), \(b^3 = (\frac{5}{2})^3 = \frac{125}{8}\) Ответ: -8; \(-\frac{1}{125}\); 0,001; -0,001; \(-\frac{27}{8}\); \(\frac{125}{8}\)
