$Question \: 1\colon \frac{25}{\sqrt{40}+\sqrt{80}} \\\\ \implies \frac{ 25 \times(\sqrt{40}+\sqrt{80})}{(\sqrt{40} - \sqrt{80})(\sqrt{40} + \sqrt{80})} \\\\\implies \frac{25(\sqrt{8\times 5} + \sqrt{10\times 2\times 2 \times 2})}{(\sqrt{40})^{2} - (\sqrt{80})^{2} } \\\\\implies \frac{25\times 2\times 2(\sqrt{10}+ \sqrt{2\times 10})}{40-80}\\\\\implies \frac{25\times 2 \times \sqrt{2} \times (\sqrt{5}+ \sqrt{10} )}{-40} \\\\\implies \frac{50\times 1.414(2.236 \:+ \: 3.162)}{-40} \\\\\implies \frac{5\times 1.414(5.398)}{-4}\\\\\implies \frac{38.163}{-4} \\\\\implies -9.540$
