OpenStudy (superhelp101):

@dan815 @Loser66

OpenStudy (anonymous):

12(2+sqrt(5))

OpenStudy (anonymous):

\[\frac{ 12 }{ \sqrt{5} -2}*\frac{ \sqrt{5}+2 }{ \sqrt{5}+2 }\]

OpenStudy (anonymous):

Do you understand?

OpenStudy (superhelp101):

oh okay i'll do it then show u

OpenStudy (anonymous):

ok

OpenStudy (superhelp101):

\[2\sqrt{5}+11\] is that it?

OpenStudy (superhelp101):

wait i am doing something wrong :(

OpenStudy (anonymous):

Denominators cancel so you are left with \[12 * \sqrt{5}+2\]

OpenStudy (anonymous):

\[12*(\sqrt{5}+2)\] *

OpenStudy (anonymous):

Now simply multiply 12 times sqrt(5) and 12 times 2

OpenStudy (anonymous):

or you can leave it like this

OpenStudy (superhelp101):

Nvm I see the denominator is 1 !!!

Thanks for the help :D
