Bài 4: Tính
a/ \(\sqrt{28 - \sqrt{63}} + 7 + \sqrt{7} - \sqrt{\left( \sqrt{7} + 1 \right)^2}\)
b/ \(\frac{3}{8} \sqrt{64} + \frac{26}{3} \sqrt{\frac{81}{169} - \sqrt{625}}\)
c/ \(9 \sqrt{\left( \frac{8}{3} \right)^2} + \sqrt{(-0,8)^2}\)
d/ \(\left( \sqrt{\frac{49}{3} - \frac{25}{3} + \sqrt{3}} \right) \sqrt{3}\)
e/ \(\sqrt{28 - \sqrt{63}}\)
f/ \(\frac{5 + \sqrt{5}}{\sqrt{5} + 1} - \sqrt{6 - 2\sqrt{5}}\)
