1. ## division

hi,
i need to know how i would work this out:

18/squareroot 3? (sorry don't know how to write square root sign on here)
im not sure how to do this so i require some help please, thanks.

2. ## Re: division

Do you want to simplify it? Then just write: $\displaystyle \frac{18}{\sqrt{3}}=\frac{6\cdot 3}{\sqrt{3}}=6\sqrt{3}$

3. ## Re: division

Alternatively,

$\displaystyle \frac{18}{\sqrt{3}}\cdot\frac{\sqrt{3}}{\sqrt{3}}= \frac{18\sqrt{3}}{3}=6\sqrt{3}$

$$\frac{18}{\sqrt{3}}=6\sqrt{3}.$$ gives $\displaystyle \frac{18}{\sqrt{3}}=6\sqrt{3}.$

Study reply #3. That explains it rather well.

what would i do if i had to write it inform of k square root 3??

8. ## Re: division

$\displaystyle 6\sqrt{3}$ is in the form $\displaystyle k\sqrt{3}$ as $\displaystyle k$ refers to an unknown integer which you are expected to determine.

so k=6?

Exactly.
