Question

Accepted Answer

সঠিক উত্তর: । ব্যাখ্যা: Total number of integers from 10 to 150 (inclusive) $=150-10+1=141$. The perfect squares in this range are: $4^2=16$, $5^2=25$, $6^2=36$, $7^2=49$, $8^2=64$, $9^2=81$, $10^2=100$, $11^2=121$, $12^2=144$. There are 9 perfect squares in this range. So, $141-9=132$ are not the squares of any integers in this range.
