Answer 1

Answer:

No,the square root of all positive integers is not always irrational.

• √9=3
• √196=14
• √225=15

So,we conclude that the square root of all positive integers are not always irrational.

More information:-

• A number which can be expressed in the form of p/q,where p and q are integers and q != 0 is called a rational number. Ex 5/6,19/70,7/5,9 etc.All whole and natural numbers are also rational numbers in other words every integer is a rational number. All terminating and all recurring decimals are also rational numbers.
• A number which cannot be expressed in the form of p/q.In other words a number which is non-terminating,non-recurring is termed as irrational number.Ex √2,√3,√5,√7 ,etc.
