Answer 2

Answer:

For 1

Step-by-step explanation:

=3/5.√7

=3√7/5

If we multiply a rational number (3) and irrational number, result will be a irrational number.

For 2

0.252525....... will be 0.25 and there will be a line over 25 which represents that 25 is repeating till infinity.

Therefore, 0.2525... is a rational number.

If we add a rational number (0.2525...)and another rational number [(√25=5) 5 is a rational number] then the result will be a rational number that is, 5.2525......
