Answer:
a real number, but not rational
Step-by-step explanation:
The square root of all prime numbers are irrational.
We want to determine whether [tex]\sqrt{7}[/tex] is rational or irrational and if it is a real number.
Since 7 is a prime number [tex]\sqrt{7}[/tex] is an irrational number.
Both rational and irrational numbers are real numbers.
Therefore [tex]\sqrt{7}[/tex] is a real number but not rational number
The second choice is correct
