let us consider root 5 +root 3 is rational
root 5 +root 3 =a÷b (where a and b r co-prime)
root 5 = a÷b-root 2
squaring on both sides
5=a^2÷b^2-2a÷b root 3+3
this contradicts root 5+ root 3 r irrational.
root 5 +root 3 =a÷b (where a and b r co-prime)
root 5 = a÷b-root 2
squaring on both sides
5=a^2÷b^2-2a÷b root 3+3
this contradicts root 5+ root 3 r irrational.
