Proof by contradiction: assume that 2 is a rational and can be written where a and b are both non-zero integers and have no common factors. √2=a/b⇒√(2b)=a⇒2b^2=a^2 2 a2 must be a even, so a must also be even, which means it can be written as 2k, where k is an...

=b^2This means that b2 is divisible by 5 and hence, b is divisible by 5.This implies that a and b have 5 as a common factor.And this is a contradiction to the fact that a and b are co-prime.Hence, √5 cannot be expressed as p/qor it can be said that v5√5 is irrational....
2+5+2√10=p²q² 7+2√10=p²q² 2√10=p²q²–7 √10=p²−7q²2q p,q are integers thenp²−7q²2qis a rational number. Then √10 is also a rational number. But this contradicts the fact that √10is an irrational number. Our assumption is incorrect...
