\[|√(5)-(5/2)| \]
OpenStudy (anonymous):
|x| = sqrt(x^2)
OpenStudy (smurfy14):
i dont see how that helps?
OpenStudy (saifoo.khan):
\[\frac{5-2\sqrt{5}}{2}\]
OpenStudy (smurfy14):
is that the answer?

Yeshh!
OpenStudy (smurfy14):
ok cool thanks! how did you get it?
OpenStudy (saifoo.khan):
Calc.
OpenStudy (anonymous):
\[(5/2)-\sqrt{5}\]
lcd=2
\[2*\sqrt{5}=2\sqrt{5}\]
so
\[(5-2\sqrt{5})/2\]
OpenStudy (smurfy14):
why do you subtract -sqrt5 from 5/2?

Ajmal's right.
OpenStudy (saifoo.khan):
bcz that is given in the equation!
OpenStudy (smurfy14):
im lost :/ the equation says sqrt5 - 5/2 not 5/2- sqrt5
OpenStudy (anonymous):
we both r wrong saif
i thought the question is (5/2)-sqrt5
but the question is sqrt5-(5/2)
lcd=2
\[2*\sqrt{5}=2\sqrt{5}\]
so
\[(2\sqrt{5}-5)/2\]
OpenStudy (saifoo.khan):
No, wait.

OpenStudy (saifoo.khan):
look there^
OpenStudy (saifoo.khan):
