Answer:
 the third one
Step-by-step explanation:
the square root of 25 is 5. 5+2 = 7.
this is a rational number (the set of all integers and fractions).
the other 2 portions contain at least one element that is not rational. and so the sum with such a number is not rational.
45 and 7 are no square numbers, and therefore the square root of these numbers contains a neverending chain of digits after the decimal point without having any repeating pattern. these are real numbers but not rational numbers.
