Answer 1

The number of non square numbers between

11² and 13² = 46 .

Step-by-step explanation:

" The number of non square numbers between n² and (n+2)² is 2n "

Here ,

i) The number of non square numbers between

11² and 12² = 2× 11 = 22 ---(1)

ii )The number of non square numbers between

The number of non square numbers between12² and 13² = 2× 12= 24 ---(2)

Therefore.,

The number of non square numbers between

The number of non square numbers between11² and 13² = 22 + 24 = 46 .
