No, because it can be expressed as a ratio or fraction. 4.7 = 4 7/10 = 47/10
47 is a whole number, integer and rational.
'47' is a prime number, so it does not have a rational square root. sqrt(47) = 6.8556546... to 9 d.p. An irrational number which cannot be converted to a quotient; that is made into a fraction. NB The square roots of prime numbers are irrational.
sqrt(47) = 6.8556546 approx. It cannot be expressed exactly as a fraction because it is an irrational number.
The sum of a rational and irrational number must be an irrational number.
rational * irrational = irrational.
The square root of 47 is an irrational number.
It is an irrational number.

+sqrt(47) is one possible answer.
sqrt(47) = 6.8556546 approx. It cannot be expressed exactly as a fraction because it is an irrational number.
Yes. The square root of any positive integer can only be either an integer (if the number, for example 49, happens to be a perfect square), or 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.
rational * irrational = irrational.
