The square root of 70 is between 8 and 9, and is irrational. This is because 70 is between the squares of 8 and 9 (64 and 81, respectively), and because the square root of 70 continues without end and without a reliable pattern. Note that this is only one out of infinite number of Irrational Numbers between 8 and 9.
It is an irrational number between 8 and 9.Es un número irracional entre 8 y 9.- (:
No, ( \frac{8}{9} ) is not irrational; it is a rational number. Rational numbers can be expressed as the quotient of two integers, and since both 8 and 9 are integers, ( \frac{8}{9} ) qualifies as rational. An irrational number cannot be expressed as a simple fraction and has a non-repeating, non-terminating decimal expansion.
3 squared is 9 and 4 squared is 16, so the square root of any whole number between 9 and 16 will be irrational.
None of them because they are both rational numbers
No, 9 plus pi is not a rational number. While 9 is a rational number, since it can be expressed as a fraction (9/1), pi is an irrational number, meaning it cannot be expressed as a fraction of two integers. The sum of a rational number and an irrational number is always irrational, so 9 plus pi remains irrational.

No.
3 squared is 9 and 4 squared is 16, so the square root of any whole number between 9 and 16 will be irrational.
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 1.125 is a rational number that can be expressed as fraction in the form of 9/8
the square root of 82
None of them because they are both rational numbers
Any addition, subtraction, multiplication, or division of rational numbers gives you a rational result. You can consider 8 over 9 as the division of 8 by 9, so the result is rational.
Yes 9 times pi is an irrational number because it can't be expressed as a fraction
What number is halfway between 8 & 9
No, it is rational.
9 is a rational number
