No it is rational because it can be expressed as a fraction in the form of 80/1
No because -80 is a rational number
Yes
The square root of 80 is not a rational number. When simplified, it becomes ( \sqrt{80} = \sqrt{16 \times 5} = 4\sqrt{5} ). Since ( \sqrt{5} ) is an irrational number, ( 4\sqrt{5} ) is also irrational. Therefore, ( \sqrt{80} ) is not rational.
-8.0 is a rational number. Irrational numbers are things such as numbers that can't be expressed as a fraction in the a/b form. Such numbers that are irrational include pi, square roots of negative numbers, etc.
An irrational number.

An irrational number.
The sum of a rational and irrational number must be an irrational number.
No. The sum of an irrational number and any other [real] number is irrational.
No, 3.56 is not an irrational number. 3.56 is rational.
rational * irrational = irrational.
-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.
A negative irrational number can be thought of as an irrational number multiplied by -1, or an irrational number with a minus sign in front of it.
