No. 2 is a rational number. Rational numbers are number that can be expressed as a division of two integers, with the denominator not being zero. 2 can be expressed as 2 divided by 1, so it is rational.
Sometimes. eg the irrational number √2 squared is 2 which is rational (2 = 2/1) eg the irrational number √(√2) squared is √2 which is irrational.
The square root of 2 is irrational, yet the product of it with itself is 2. So the answer is no.
Any irrational number multiplied by 0.5 will produce another irrational number. For example, if you take the irrational number √2 and multiply it by 0.5, you get 0.5√2, which is also irrational. Thus, any irrational number, when multiplied by 0.5, will result in an irrational number.
Any irrational number multiplied by 0.4 will produce an irrational number. For example, if you take the irrational number √2 and multiply it by 0.4, the result, 0.4√2, will also be irrational. Thus, any irrational number you choose will suffice.

Sometimes. eg the irrational number √2 squared is 2 which is rational (2 = 2/1) eg the irrational number √(√2) squared is √2 which is irrational.
The product of two irrational numbers may be rational or irrational. For example, sqrt(2) is irrational, and sqrt(2)*sqrt(2) = 2, a rational number. On the other hand, (2^(1/4)) * (2^(1/4)) = 2^(1/2) = sqrt(2), so here two irrational numbers multiply to give an irrational number.
The square root of 2 is irrational, yet the product of it with itself is 2. So the answer is no.
No.3*sqrt(2) and sqrt(2) are irrational. But their quotient is 3, which is rational.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
Yes. sqrt(2) + sqrt(2) = 2*sqrt(2), an irrational number.
Any irrational number, added to 0.4 will give an irrational number.

Yes, the square root of 2 is an irrational number.
It isn't. 2 is perfectly rational.You are confused with the square root of 2, which is an irrational number.
Not always. For example sqrt(2) and 1/sqrt(2) are both irrational, but their product is the rational number 1.
Any irrational number will, eg √2, π, e.
