1. $$\frac{2,88 - 44,5}{0,288 \cdot 4,45} = \frac{-41,62}{1,2816} = -32,475$$ 2. Недостаточно данных для решения. Нужно выражение. 3. $$q(b-2) - q(b+2) = 3(b-2) - 3(b+2) = 3b - 6 - 3b - 6 = -12$$ 4. $$(\frac{1}{4} - 2) \cdot 6\frac{2}{3} = -\frac{7}{4} \cdot \frac{20}{3} = -\frac{7 \cdot 5}{3} = -\frac{35}{3} = -11\frac{2}{3}$$ 5. $$(252^2 - 23^2) : 275 = (252 - 23)(252 + 23) : 275 = 229 \cdot 275 : 275 = 229$$ 6. $$\frac{(11a)^2 - 11a}{11a^2 - a} = \frac{121a^2 - 11a}{11a^2 - a} = \frac{11a(11a - 1)}{a(11a - 1)} = 11$$ 7. $$p(b) = (b + \frac{6}{b})(6b + \frac{1}{b})$$ $$p(\frac{1}{6}) = (\frac{1}{6} + \frac{6}{\frac{1}{6}})(6 \cdot \frac{1}{6} + \frac{1}{\frac{1}{6}}) = (\frac{1}{6} + 36)(1 + 6) = \frac{217}{6} \cdot 7 = \frac{1519}{6} = 253\frac{1}{6}$$ 8. $$(\frac{5}{3} - 2) : \frac{5}{21} = (\frac{5}{3} - \frac{6}{3}) : \frac{5}{21} = -\frac{1}{3} \cdot \frac{21}{5} = -\frac{7}{5} = -1\frac{2}{5}$$ 9. $$6(p(5x) - 5p(x+3)), p(x) = x+5$$ $$6((5x + 5) - 5((x+3) + 5)) = 6(5x + 5 - 5x - 40) = 6(-35) = -210$$ 10. $$(-2\frac{3}{4} - \frac{3}{8}) \cdot 160 = (-2\frac{6}{8} - \frac{3}{8}) \cdot 160 = -2\frac{9}{8} \cdot 160 = -\frac{25}{8} \cdot 160 = -25 \cdot 20 = -500$$
