Answer 1

a=$a=\sqrt{2^{4} } +\sqrt{\frac{5}{0.0(2)} } +\sqrt{\frac{55}{0.0(02)} } +\sqrt{\frac{555}{0.0(002)} } =2^{2} +\sqrt{\frac{5}{\frac{2}{90} } } +\sqrt{\frac{55}{\frac{2}{990} } } +\sqrt{\frac{555}{\frac{2}{9990} } } = 4+\sqrt{15^{2} } +\sqrt{15^{2}*11^{2}} +\sqrt{15^{2}*111^{2}} = 4+15+165+1665=1849$
