Real Easy Question. Just tell me how to do these kind of questions.
\[\sqrt{3+\sqrt{5}}\]
wat u want to do ?
How to solve this?
you can remove one root by squaring it
does that equal something ? to solve u need an equation
ya you need to find the square roots
I will give options w8
okie
well first if I'm correct at all on this you could find the square root of 5 and then take that plus 3 and find the square root of tht??
\[a) \sqrt{2}+1\] \[b)\sqrt{\frac{ 5 }{ 2 }}\] \[c) \sqrt{\frac{ 7 }{ 2}}-\sqrt{\frac{ 1 }{2 }}\] \[d) \sqrt{\frac{ 9 }{ 2 }}-\sqrt{\frac{ 3 }{ ? }}\]
in option d question mark replaces 2
and, where is the full question ?
LOL It was l\[\sqrt{3+\sqrt{5}}\]=
im not sure how does that ever equal to one of the given choices :|
sorry i give up
No prob
@uri @thomaster @mathstudent55 @RANE @RoseDryer @shrutipande9
ok key is to tranform inside as a perfect square \[\sqrt{3+\sqrt{5}} = \sqrt{\frac{1+2\sqrt{5}+\sqrt{5}^{2}}{2}} = \sqrt{\frac{(1+\sqrt{5})^{2}}{2}} = \frac{1+\sqrt{5}}{\sqrt{2}}\] that is still not equal to any of given answers though ....may be a typo?
HEY sorry 2nd option is incomplete. i guess ur answer is right.
that was awesome @dumbcow :)
\[\sqrt{\frac{ 5 }{ 2 }}+\sqrt{\frac{ 1 }{ 2 }}\]
