Question
The simplest rationalising factor of \[2\sqrt{5}-\]\[\sqrt{3}\] is
Options
\[2\sqrt{5} + 3\]
\[2\sqrt{5} + \sqrt{3}\]
\[\sqrt{5} + \sqrt{3}\]
\[\sqrt{5} - \sqrt{3}\]
Solution
We know that rationalization factor for `asqrtb - sqrtc` is .`asqrtb +sqrtc` Hence rationalization factor of `2sqrt5-sqrt3`
