Rational

If you multiply or divide an irrational number - such as pi - by ANY rational number (except zero), you will ALWAYS get an irrational number.

Irrational number is a number that cannot be expressed as a fraction of two integers. Every single number you provided can be expressed as rational: 0.5 = 1/2 13 = 13/1 34 = 34/1 0.6 = 3/5 None of them is irrational.

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.

No because it can be expressed as a negative fraction in the form of -13/2

5.4 = 5 2/5 = 27/5 so it is a rational number.

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.

No.3*sqrt(2) and sqrt(2) are irrational. But their quotient is 3, which is rational.

The square root of 2 is irrational, yet the product of it with itself is 2. So the answer is no.

It is equal to 21/2 which is a rational number

It is irrational because when you divide 2 by 8 you get a terminating decimal,0.205.
