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.
Solution:
The square roots of all positive integers are not irrational numbers.
For example, √4 = ± 2 which indicates that either 2 or -2 can be the square root of 4.
We see that both 2 and -2 are rational numbers because they can be expressed as 2/1 and -2/1 respectively.
