Вычислите значение:

а) \( p^2 \) при \( p = -4 \) \( p^2 = (-4)^2 = 16 \) \( p^2 \) при \( p = -1\frac{1}{9} = -\frac{10}{9} \) \( p^2 = \left(-\frac{10}{9}\right)^2 = \frac{100}{81} = 1\frac{19}{81} \) \( p^2 \) при \( p = 0,6 = \frac{6}{10} = \frac{3}{5} \) \( p^2 = (0,6)^2 = (\frac{3}{5})^2 = \frac{9}{25} = 0,36 \) \( p^2 \) при \( p = -0,8 = -\frac{8}{10} = -\frac{4}{5} \) \( p^2 = (-0,8)^2 = (-\frac{4}{5})^2 = \frac{16}{25} = 0,64 \) \( p^2 \) при \( p = -2\frac{1}{3} = -\frac{7}{3} \) \( p^2 = \left(-\frac{7}{3}\right)^2 = \frac{49}{9} = 5\frac{4}{9} \) \( p^2 \) при \( p = 3\frac{1}{5} = \frac{16}{5} \) \( p^2 = \left(\frac{16}{5}\right)^2 = \frac{256}{25} = 10\frac{6}{25} = 10,24 \) б) \( b^3 \) при \( b = -2 \) \( b^3 = (-2)^3 = -8 \) \( b^3 \) при \( b = -\frac{2}{3} \) \( b^3 = \left(-\frac{2}{3}\right)^3 = -\frac{8}{27} \) \( b^3 \) при \( b = 0,1 = \frac{1}{10} \) \( b^3 = (0,1)^3 = (\frac{1}{10})^3 = \frac{1}{1000} = 0,001 \) \( b^3 \) при \( b = -0,1 = -\frac{1}{10} \) \( b^3 = (-0,1)^3 = (-\frac{1}{10})^3 = -\frac{1}{1000} = -0,001 \) \( b^3 \) при \( b = -1\frac{1}{5} = -\frac{6}{5} \) \( b^3 = \left(-\frac{6}{5}\right)^3 = -\frac{216}{125} = -1\frac{91}{125} = -1,728 \) \( b^3 \) при \( b = 2\frac{1}{2} = \frac{5}{2} \) \( b^3 = \left(\frac{5}{2}\right)^3 = \frac{125}{8} = 15\frac{5}{8} = 15,625 \)
