c) \(2^3 + 3 \cdot \left(-\frac{1}{2}\right)^6 - \left(\frac{1}{2}\right)^2 \cdot 4 + \left[(-2)^2, \frac{1}{2}\right] : 8\)

Bài 9: Tính

a) \(\left(-\frac{3}{8} + \frac{5}{32}\right) \cdot \left(-\frac{4}{5} - \frac{3}{5}\right) + \left(\frac{5}{32} + \frac{27}{32}\right) \cdot \left(\frac{5}{4}\right)\)

b) \(\frac{5^{11} \cdot 7^{12} + 5^{11} \cdot 7^{11}}{5^{12} \cdot 7^{12} + 9 \cdot 5^{11} \cdot 7^{11}} + \frac{9}{11}\)
