[tex]\sin 15^\circ+\sin 75^\circ=2\sin 45^\circ\cos 30^\circ=2\cdot\frac{\sqrt{2}}{2}\cdot\frac{\sqrt{3}}{2}=\frac{\sqrt{6}}{2}[/tex]
[tex]\left(\frac{\sqrt{6}}{2}\right)^{6}=\frac{6^{3}}{2^{6}}=\frac{216}{64}=\frac{27}{8}[/tex]
[tex]\left(\frac{\sqrt{6}}{2}\right)^{6}=\frac{6^{3}}{2^{6}}=\frac{216}{64}=\frac{27}{8}[/tex]
