1/sqrt(2) + 3/sqrt(8) + 6/sqrt(32)

= (1sqrt(2) + 3sqrt(2) + 6sqrt(2))/sqrt(2)

= 10sqrt(2)/sqrt(2)

= 10sqrt(2^1)

= 10sqrt(2)

$\frac{1}{\sqrt2}+\frac{3}{\sqrt{8}}+\frac{6}{\sqrt{32}}\\\\ \frac{1}{\sqrt2}+\frac{3}{2\sqrt{2}}+\frac{6}{4\sqrt{2}}\\\\ \frac{1}{\sqrt2}(1+\frac{3}{2}+\frac{6}{4})\\\\ \frac{\sqrt2}{2}4\\\\ 2\sqrt2$
