Question

1 divided by root6 - root11 + root5. urgent

Answer 1

1/√6      -  √11        + √5

LCM = √6

(1 - (√6)*(√11) + (√5)*(√6) ) / √6


(1 - √(6*11)   + √(5*6) )/ √6


Rationalize the surd by multiplying top and bottom by  √6

((1 - √(6*11)   + √(5*6) )/ √6)    * (√6/√6)


(√6 -  √(6*6*11) + √(5*6*6)) /  √6

(√6 -  6√(11) + 6√(5)) /  6

So answer is:

(√6 -  6√11 + 6√5) / 6
