    ⇔ $($$\frac{6\sqrt{6}}{\sqrt{9}}$$-$$\frac{5\sqrt{32}}{\sqrt{25}}$$+$$\frac{14\sqrt{18}}{\sqrt{49}}$$)$$.$ $\frac{1}{\sqrt{2}}$ 
    ⇔ $($$2\sqrt{6}$ $-$ $\sqrt{32}$ $+$ $2\sqrt{18}$$)$ $.$ $\frac{1}{\sqrt{2}}$ 
    ⇔ $\frac{2\sqrt{6} – \sqrt{32} + 2\sqrt{18}}{\sqrt{2}}$  
    ⇔ $2$ $+$$2\sqrt{3}$
