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))

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

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

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

Simplify : (x+sqrt(x^(2)-1))^(7) + (x-sqrt(x^(2)-1))^(7)

Simplify : (x + sqrt(x^(2) - 1))/(x - sqrt(x^(2) -1)) + (x - sqrt(x^(2) -1))/(x + sqrt(x^(2) -1)) If the result of the simplification is equal to 14, then find the value of x
