Answer:

[tex]\frac{23\sqrt{10} }{10}[/tex]

Step-by-step explanation:

[tex]\frac{3}{\sqrt10} }+\sqrt{40} \\\frac{3*\sqrt{10} }{\sqrt{10} *\sqrt{10} } +\sqrt{40} \\\frac{3\sqrt{10} }{\sqrt{10*10} } +\sqrt{40} \\\frac{3\sqrt{10} }{10} +2\sqrt{10} \\\frac{3\sqrt{10} }{10}+\frac{2\sqrt{10} }{1} \frac{*10}{*10} \\\frac{3\sqrt{10} }{10}+\frac{20\sqrt{10} }{10} \\\frac{3\sqrt{10}+20\sqrt{10} }{10}\\\frac{23\sqrt{10} }{10}[/tex]

Hope this helps you.
