Question

are the square roots of all positive integers irrational? If not give an example of the square root of a number that is a rational number

Answer 1

there are too many positive integers whose square root is rational like 4,9,16,25,..........etc.

Answer 2

No, the square roots of all positive integers are not irrational.

For example,

√4 = 2 is rational.

9 = 3 is rational.

Hence, the square roots of positive integers 4 and 9 are not irrational. ( 2 and 3, respectively).
