Question

Find the number of non square numbers lying between

40² and 41².​

Answer 1

Answer:

To find the number of non square numbers between n² and (n+1)², we multiply n by 2.

So, number of non square numbers = 2n

Here n = 40.

2 × 40 = 80

Therefore, there are 80 non square numbers between (40)² and (41)².
