$$\frac{(4.53-3.07)^{2}}{(3.07-2.15)(2.15-4.53)}+\frac{(3.07-2.15)^{2}}{(2.15-4.53)(4.53-3.07)}+\frac{(2.15-4.53)^{2}}{(4.53-3.07)(3.07-2.15)}$$ is simplified to
$$\sqrt{2+\sqrt{3}}\times\sqrt{2+\sqrt{2+\sqrt{3}}}\times\sqrt{2+\sqrt{2+\sqrt{2+\sqrt{3}}}}\times\sqrt{2-\sqrt{2+\sqrt{2+\sqrt{3}}}}$$ is equal to
