Is that two divided by the square root of one half?

3. diamondboy

yes

4. anonymous

You find the square root of one half which is 0.70710678118

$$\dfrac{2}{\sqrt{\frac{1}{2}}}=\dfrac{\sqrt{4}}{\sqrt{\frac{1}{2}}}=\sqrt{\dfrac{4}{\frac{1}{2}}}=\sqrt{4*2}=\sqrt{4}\sqrt{2}=2\sqrt{2}$$

God bless u @zzr0ck3r

7. anonymous

lol i tried to give you the decimal response I'm sorry.

8. diamondboy

That works for me because SQRT of 4=2

9. diamondboy

It's ok @TheBallisticOne

I was about to ask u if I didn't have a calc how could i solve it

or multiply top and bottom with the denominator since we can't leave the radical sign at the denominator $\huge\rm \frac{ 2 }{ \sqrt{\frac{1}{2}} } \times \frac{ \sqrt{\frac{1}{2}} }{\sqrt{\frac{1}{2}} } =\frac{ 2\sqrt{\frac{1}{2}} }{\frac{1}{2} }$ multiply top with the reciprocal of the denominator $2\sqrt{\frac{1}{2} } \times 2 = 4 \sqrt{\frac{1}{2}}$ $\sqrt{\frac{a}{b}} =\frac{ \sqrt{a} }{ \sqrt{b} }$ so$\frac{ 4\sqrt{1} }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} }$ once again multiply top and bottom with the denominator $\frac{ 4\sqrt{2} }{ 2 }=\frac{ \cancel{4}\sqrt{2} }{ \cancel{2}}=2\sqrt{2}$
