\(\sqrt{1.3} +\sqrt{1300}+\sqrt{0.013}\)
= \(\sqrt{\frac{130}{100}}\) + \(\sqrt{13\times100}\) + \(\sqrt{\frac{130}{10000}}\)
= \({\frac{\sqrt{130}}{\sqrt{100}}}\) + \(\sqrt{13}\) x \(\sqrt{100}\) + \(\frac{\sqrt{130}}{\sqrt{10000}}\)
= \(\frac{11.40}{10}\) + 3.605 x 10 + \(\frac{11.40}{100}\)
= 1.14 + 36.05 + 0.114 = 37.304
