Tính:   \(D=3\frac{5}{3}.20\frac{3}{41}-7\frac{3}{41}.3\frac{5}{41}+\left(-\frac{1}{2}\right)\)

Tính bằng cách thuận tiện nhất:  \(\frac{2^{12}.3^5-4^6.3^6}{2^{12}.9^3+8^4.3^5}\)

Tính:  \(F=-\frac{5}{\sqrt{196}}-\frac{5}{\left(2\sqrt{21}\right)^2}-\frac{\sqrt{25}}{204}-\frac{\left(\sqrt{5}\right)^2}{374}\)

3 câu này mình đều tính rồi nhưng kết quả cao hoặc k ra được đáp số, mong các bạn gíup đỡ!
