$$ \frac{0,5^{\sqrt{10}-1}}{2^{-\sqrt{10}}} = \frac{(\frac{1}{2})^{\sqrt{10}-1}}{2^{-\sqrt{10}}} = \frac{(2^{-1})^{\sqrt{10}-1}}{2^{-\sqrt{10}}} = \frac{2^{-(\sqrt{10}-1)}}{2^{-\sqrt{10}}} = \frac{2^{-\sqrt{10}+1}}{2^{-\sqrt{10}}} = 2^{-\sqrt{10}+1 - (-\sqrt{10})} = 2^{-\sqrt{10}+1 + \sqrt{10}} = 2^1 = 2$$
