Bài 8: Thực hiện phép tính
1) \(\sqrt{\frac{225}{3^2}} \cdot \left(-\sqrt{\frac{1}{4}} \cdot \frac{1}{5} + \frac{6}{\sqrt{64}} + \frac{3 \cdot \sqrt{3^2}}{4}\right)\)
2) \(3 + \frac{\sqrt{4}}{\sqrt{1}} \left[1 + \frac{27}{3}: \left(2 - 1: \left(3 + \frac{1}{1 - \sqrt{9}}\right)\right)\right]\)
3) \(A = \left[-\frac{7}{5} + \frac{1}{\sqrt{(-2)^2}} + (0,5)^2\right] \cdot \left[-\left(\frac{4}{10} + \frac{3}{2} - 0,75\right)\right]\)
4) \(A = \left(-\frac{3}{4}\right)^2 \cdot (-16) \cdot (2019 - 2020)^{2019} - \sqrt{(-10)^2}\)
5) \(A = \left(-\frac{1}{2}\right)^2 \cdot \sqrt{16 - 3^2 \cdot \sqrt{0,01} + (2)^2} \cdot \left[0,0(6) + \frac{13}{30}\right]\)
