It is a rational number because it can be expressed as an improper fraction in the form of -80/1
No, because an integer is a whole number and it's opposite (negative or positive). The square root of 80 is not a whole number.
Well, lets see. First we have to divide 80 by 2 as such: 80/2 = 40. Then we square root 40, which leads us to our final answer of 6.32455532.
No, the square root of 6400 is 80, and 3200 squared is 10240000.
-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 is a number which cannot be expressed as a fraction made of integers. These numbers generally have infinite decimals with no pattern to them whatsoever. The easiest way, I think, to make an irrational number is to take the square root of a number between the squares of your parameters, in this case between 64 and 81. Thus a number such as square root(72), which is 8.485281..., or square root(80), which is 8.944571..., will do nicely.

No, because an integer is a whole number and it's opposite (negative or positive). The square root of 80 is not a whole number.
A negative number cannot have a square root in basic mathematics. However, in more advanced mathematics, you will study complex numbers. And there you will find that the square roots of -80 are ± 8.944*i where i is the imaginary square root of -1.Incidentally, ± 8.944 are the square roots of +80.
Square root of 81
no. 80 is a rational number
Well, lets see. First we have to divide 80 by 2 as such: 80/2 = 40. Then we square root 40, which leads us to our final answer of 6.32455532.
square root of 125/80 = 1.25 or 5/4
√80 = 8.94427191
