Question

how many non square are there between 144 and 169​

Answer 1

It is clear that 12^2 = 144 and 13^2 = 169. Hence, there are no squares between them.

Therefore, there are 24 square numbers between them.

Answer 2

There are 24 non-square numbers between 144 and 169.

Given:

Two numbers 144 and 169

Find:

The number of the non-square is there between 144 and 169​

Solution:

We know 12 and 13 are consecutive natural numbers.

12² = 144 and 13² =169

So there is no other square number between 144 and 169.

That means all the numbers between 144 and 169 are non-square numbers.

169-144 =25

Hence the number of non square numbers = 25-1 = 24 (excluding the extreme number)

The number of non-square numbers between 144 and 169 is 24
