Question

Please solve all the questions urgently

Answer 1

1){√5 + √6}^2
using property = (a+b}^2 = a^2 +b^2 +2ab
after putting values,
u will get,
11+2√30
A.T.Q, we have,
a=11
and b=2
2) I don't have any idea about it.
3) x=2+√3
putting formula,
(a+b)^3= a^3 + b^3 +3ab(a+b)
by solving it u will be getting the ur ans.
4) -√2 +√3 is ur ans.
5)use formula
(a^2+b^2+2ab) + (a^2+ b^2 - 2ab)by solving it u will get ur ans.
