If \( \sqrt{x} - \frac{1}{\sqrt{x}} = \sqrt{3} \) , then what is the value of \( x^4 + \frac{1}{x^4} \, ? \)
If A = 10°, then what is the value of
\(\frac{12\sin 3A + 5\cos(5A - 5^\circ)}{9\sin\frac{9A}{2} - 4\cos(5A + 10^\circ)} \, ?\)
\( \frac{6\sqrt{2} + 5}{9 - 2\sqrt{2}} \)
\( \frac{6\sqrt{2} - 5}{9 - 2\sqrt{2}} \)
\( \frac{9 - 2\sqrt{2}}{6\sqrt{2} + 5} \)
\( \frac{6\sqrt{2} + 5}{9 + 2\sqrt{2}} \)
