Answer 1

Hope it helps u dear!!!!!!

Answer 2

Let us assume that √2+√5 is a rational number.we know that every rational number can be expressed in the form a÷b where b not equal to 0 and a and b are co primes





Here RHS is a rational number and √10 is an irrational number and not equal.Hence our assumption is wrong.√2+√5 is a rational number
