Integers are whole numbers, therefore they are not irrational

Some irrational numbers can be multiplied by another irrational number to yield a rational number - for example the square root of 2 is irrational but if you multiply it by itself, you get 2 - which is rational. Irrational roots of numbers can yield rational numbers if they are raised to the appropriate power

Some would say that there is no intersection. However, if the set of irrational numbers is considered as a group then closure requires rationals to be a proper subset of the irrationals.

Every irrational number, when multiplied by 0.4 will produce an irrational number.

It is true and false. It cannot be proved.
