sqrt(6+sqrt(6+sqrt(6+...)))

If tan theta=sqrt(6+sqrt(6+sqrt6+...)) then sec^2 theta=

Rationalise the denominator of (sqrt(7)-sqrt(6))/(sqrt(7)+sqrt(6))

sqrt(7+2sqrt(6))+sqrt(7-2sqrt(6)) =______.

(sqrt(6+2sqrt(5)))(sqrt(6-2sqrt(5)))

(sqrt(6)+sqrt(5)+ 1/(sqrt(6)+sqrt(5)))^2

If (sqrt(5 + 2sqrt6)- sqrt(5 - 2 sqrt6))/(sqrt(5 + 2 sqrt6)+ sqrt(5 - 2 sqrt6)) = sqrt((x)/(16)) , then x = _____

If a=(sqrt(7)-sqrt(6))/(sqrt(7)+sqrt(6)) and b=(sqrt(7)+sqrt(6))/(sqrt(7)-sqrt(6)), then find the value of a^(2)+b^(2)+ab
