To simplify sqrt(1+x) + sqrt(1-x), we can use the formula for the sum of square roots. By squaring the expression, we can eliminate the square roots.

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

Simplifying further, we have:

= 2 + 2(sqrt(1+x))(sqrt(1-x))

Therefore, sqrt(1+x) + sqrt(1-x) cannot be simplified further.
