Canceling out $\sqrt{2}$ with $2$

85 Views Asked by At

Factor out common term $2$ $$= \frac{2(2+\sqrt{2})}{\sqrt{2}}$$ Cancel the common term $\sqrt{2}$ $$= \sqrt{2}(2+\sqrt{2})$$ canceling out $\sqrt{2}$ with the number $2$, what am I missing? Thank you.

$$\frac{2}{\sqrt{2}}=\frac{2}{\sqrt{2}}\times\frac{\sqrt{2}}{\sqrt{2}}=\frac{2\times\sqrt{2}}{\sqrt{2}\times\sqrt{2}}=\frac{2\times\sqrt{2}}{2}=\frac{2}{2}\times\sqrt{2}=\sqrt{2}$$
