Question

How many non-square natural numbers are there between (11)^2 and (13)^2?

Answer 1

To find the non - square natural numbers between (11)^2 and (13)^2 we have to multiply the smaller number by 2.
Therefore, (11)^2 = 121 , (13)^2 = 169
121×2 = 242
Hence, 242 non - square numbers lie between (11)^2 and (13)^2.
