It will be irrational.

If you multiply a rational and an irrational number, the result will be irrational.

Irrational. If you multiply a rational number by an irrational number, you will always get an irrational number (except if the rational number happens to be zero).

Yes.

The product of an irrational number and a rational number, both nonzero, is always irrational

Yes, but only if the rational number is 0.

-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.

Yes. Any time you multiply a rational number by an irrational number, you get an irrational number - unless the rational number is zero.

-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.

No.

no

Sqrt(2) is irrational. Multiply by sqrt(4.5). Result is 3 which is rational.

No irrational number can turn into a rational number by itself: you have to do something to it. If you multiply any irrational number by 0, the answer is 0, which is rational. So, given the correct procedure, every irrational number can be turned into a rational number.

If you multiply an irrational number by ANY non-zero rational number, the result will be irrational.

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

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

No. The number pi is irrational, and if you multiply an irrational number by a non-zero rational number (in this case, -2), you will get another irrational number.As a general guideline, most calculations that involve irrational numbers will again give you an irrational number.

No; since pi is irrational if you multiply it by a rational number it is still irrational
