no.
sqrt(5) * sqrt(5) = 5
5 is rational and sqrt(5) is not
and no
1 + sqrt(5) + (1- sqrt(5) ) = 2
2 is rational and both 1+ sqrt(5) and 1 - sqrt(5) are irrational.

The answer might be rational or irrational. Remember, square roots are not the only irrational numbers - you also have numbers like pi, e, and cube roots.

the answer might be rational
like
[sqr(3) + sqr(5 ) ] [ sqr(3) - sqr(5 ) = 3 - 5 = -2
