Question

there are P perfect square natural numbers which are between 100 and 1000 which are squares of prime natural numbers. write the value of P.​

Answer 1

Answer:Not including 100, there are 21 square numbers. Lets see how.

We know that 30² = 900.

Lets try the next squared number 31 --> 31² = 961

Lets try the next squared number 32 -->32² =  1024 (this goes beyond our criteria)

So we can deduce that squaring of numbers between 11 and 31 will give us perfect square numbers between 100 and 1000. And there are 21 such numbers: 11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31.

The squares of all these numbers will lie between 100 and 1000.
