Question

Efetuando-se a soma \dpi{100} \sf \frac{4}{\sqrt2}+\frac{9}{\sqrt3}, obtém-se

Answer 1

$\frac{4}{\sqrt{2} }+\frac{9}{\sqrt{3} } =$

$\frac{\sqrt{16} }{\sqrt{2} }+\frac{\sqrt{81} }{\sqrt{3} }=$

$\frac{\sqrt{8.2} }{\sqrt{2} }+\frac{\sqrt{27.3} }{\sqrt{3} }=$

$\frac{\sqrt{8}.\sqrt{2} }{\sqrt{2} }+\frac{\sqrt{27}.\sqrt{3}}{\sqrt{3}}=$

$\sqrt{8}+\sqrt{27}=$

$\sqrt{4.2}+\sqrt{9.3}=$

$2\sqrt{2}+3\sqrt{3}$
