An irrational number is a number that has no definite end. 4.5 has a definite end. THis makes it a rational number.
irrational
Yes, the square root of 45 is irrational. It can be simplified to ( \sqrt{45} = \sqrt{9 \times 5} = 3\sqrt{5} ). Since ( \sqrt{5} ) is an irrational number, multiplying it by 3 still results in an irrational number. Therefore, ( \sqrt{45} ) is irrational.
irrational
45 is an integer which is a rational number. So the question makes no sense.
All integers are rational, since they can be written, for example, in the form 45/1.

The square root of 45
-.45 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
It is irrational
It is 3 times sq rt 5 which is an irrational number
45 is real, rational, whole, natural, odd, composite, and an integer.
45 is not a perfect square number. the closest perfect squares are 49 and 36. But it is the square of the irrational number 6.708204... (an infinite, non-terminating, non-repeating decimal).
