The square root of 2 is "irrational" (cannot be written as a fraction) ... because if it could be written as a fraction then we would have the absurd case that the fraction would have even numbers at both top and bottom and so could always be simplified.

Let us suppose that √2+√3 is rational. is rational, and so √3 is rational. This contradicts the fact √3 is irrational. Hence, √2+√3 is irrational.

Answer. 3+√2 = a/b ,where a and b are integers and b is not equal to zero .. therefore, √2 = (3b - a)/b is rational as a, b and 3 are integers.. ... So, it concludes that 3+√2 is irrational..

A rational number can be written in the form of p/q. p,q are integers then (p-2q)/q is a rational number. ... Therefore,2+√3 is an irrational number.

So if you find the squares of 2 and 3, that is 4&9, all the square roots of the numbers in between are 4&9 are irrational. So sqrt5, sqrt6, sqrt 7 and sqrt8 are irrational numbers between 2 and 3.

Let us assume to the contrary that √3 is a rational number. where p and q are co-primes and q≠ 0. This means that 3 divides p2. ... This demonstrates that √3 is an irrational number.

The square root of 110 is a rational number if 110 is a perfect square. It is an irrational number if it is not a perfect square. Since 110 is not a perfect square, it is an irrational number.

results to an irrational no. ... therefore our supposition is wrong hence √2 is irrrational no ......and as a result 5√2 is an irrational no.

A short proof of the irrationality of √2 can be obtained from the rational root theorem, that is, if p(x) is a monic polynomial with integer coefficients, then any rational root of p(x) is necessarily an integer. Applying this to the polynomial p(x) = x2 − 2, it follows that √2 is either an integer or irrational.

Since p and q are integers (rational no.) ,5q – p/3q should also be a rational no. Therefore 5-3√2 is an irrational no.

Because there is a contradiction, the assumption (1) that √2 is a rational number must be false. This means that √2 is not a rational number; i.e., √2 is irrational.

So 1/2+root 3 = a/b where a and b are irrationals. since rhs is a rational number root 3 should be also rational . ... So our assumption is wrong and hence we conclude that is irrational.

according to closure property of irrational no. Sum of two irrational no. is also an irrational no. ⇒ 2√3 + √5 is an irrational no.
