if ` tanalpha=1/(sqrt(x(x^2+x+1))), tanbeta=(sqrtx)/(sqrt(x^2+x+1)` and `tangamma=sqrt(x^-3+x^-2+x^-1)` then `alpha+beta=`

if tan alpha=(1)/(sqrt(x(x^(2)+x+1))),tan beta=(sqrt(x))/(sqrt(x^(2)+x+1)) and tan gamma=sqrt(x^(-3)+x^(-2)+x^(-1)) then alpha+beta=

If tan alpha = (1)/(sqrt (x (x ^(2) + x + 1))). tan beta = (sqrtx)/(sqrt (x ^(2) + x +1))and tan y = (x ^(-3) + x ^(-2)+ x ^(-1)) ^(1//2), then for x gt 0

a+1=2sqrt(a)x then (sqrt(x^(2)-1))/(x-sqrt(x^(2)-1))=

sqrt(x)-1/sqrt(x)= x=2-sqrt(3)

y=(sqrt(x)+(1)/(sqrt(x)))(1+x+x^(2))

If x>1 and (sqrt(x+1)+sqrt(x-1))/(sqrt(x+1)-sqrt(x-1))=2 then x
