Bài 1: Tính
1) \(\left( \frac{11}{15} + \frac{2}{3} - \frac{1}{5} \right) \left( \frac{1}{2} - \frac{2}{3} \right)^{2}\)
2) \(\frac{4^{5} \cdot 9^{4} - 2^{6}}{2^{10} \cdot 3^{3} + 6^{8} \cdot 20}\)
3) \((-2)^{3} + \frac{-1}{2} - 5 + 64\)
4) \(25\left(-\frac{1}{5}\right)^{3} + \frac{1}{5} - 2 \cdot \left(-\frac{1}{2}\right)^{2} - \frac{1}{2}\)
5) \(2 - \left(-\frac{7}{9}\right)^{0} + \left(\frac{1}{2}\right)^{2} : 2\)
6) \(\frac{17}{-26} \cdot \left( \frac{1}{6} - \frac{5}{3} \right) \cdot 17 \cdot \frac{13}{20} \cdot \frac{3}{\left(2 \cdot 5 - \frac{1}{4}\right)}\)
