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

$\sqrt{2\\}$Answer:

No...

Step-by-step explanation:

Some positive integers can have an irrational square root,

such as $\sqrt{3}$,$\sqrt{5}$,$\sqrt{\pi }$, etc.

However, the square root of numbers

such as -

$\sqrt{4}$=2

$\sqrt{25}$=5

$\sqrt{49}$=7

$\sqrt{100}$=10

$\sqrt{225}$=15 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)
