Simplify: `(x+sqrt(x-1))^6+(x-sqrt(x-1))^6`

Simplify (x+sqrt(x^(2)-1))/(x-sqrt(x^(2)-1))+(x-sqrt(x^(2)-1))/(x+sqrt(x^(2)-1))

Simplify : ( sqrt( x +1 ) - sqrt(x-1) ) / ( sqrt(x + 1 ) + sqrt( x -1) )

If alpha and beta be the coefficients of x^6 and x^2 respectively in the expansion of (x+sqrt(x^2 -1))^6+(x-sqrt(x^2 -1))^6 , then

1/(sqrt(6x-5))

Express: ((x+sqrt(x^2+1))^6+ (x-sqrt(x^2+1))^6) as a polynomial in x

Evaluate the following: (x+sqrt(x^(2)-1))^(6)+(x-sqrt(x^(2)-1))^(6)

Find the number of terms in the expansion of (x+sqrt(x^(2)-1))^(6)+(x-sqrt(x^(2)-1))^(6)

(x+sqrt(x^(2)-1))^(6)+(x-sqrt(x^(2)-1))^(6)

Simplify : 1/ ( 1 + sqrt (x) )

sqrt(x-6)-sqrt(10-x)>=1
