how would you solve this? 7/radical 12 ? i know you multiply both sides by radical 12 but i dont know what to do after this?

Question

hartnn · Answer

both sides ? you mean numerator and denominator ?

hartnn · Answer

so what you have in denominator ?

anonymous · Answer

the denominator is radical 12 and yeah thats what i meant

hartnn · Answer

after you  multiply num and denom by sqrt 12
you will have $\sqrt {12}\times \sqrt {12}$
in the denominator, right ?

hartnn · Answer

correct!
simplify denominator and you're done
hint : $\sqrt x \times \sqrt x =x$

anonymous · Answer

would the bottom just equal to 12 now?

hartnn · Answer

yes!

anonymous · Answer

would $$\sqrt{12} = 3\sqrt{2}\sqrt{2}$$

hartnn · Answer

no.... 
where did the square root for 3 go ?

hartnn · Answer

$\sqrt {12}= \sqrt {3\times 4} = \sqrt 3 \sqrt 4 =... ?$

hartnn · Answer

and whats the square root of 4 ?

anonymous · Answer

2

hartnn · Answer

so, $\sqrt {12}=2\sqrt3$

hartnn · Answer

so everything clear till here ?
$\dfrac{7\times 2\sqrt3}{12}$
?

hartnn · Answer

what gets cancelled out ?

hartnn · Answer

you still there ? or did i scare you off ?
