How many four digit palindromes are perfect squares?

There are no four-digit perfect squares that are palindromes.


How many three digit positive integers are square numbers?

102 = 100 which is the first possible three digit number that is a perfect square. 312 = 961 which is the last possible three digit number that is a perfect square. So there are 22 three digit positive numbers that are perfect squares.


How many 5-digit integers are perfect squares?

The smallest 5-digit integer perfect square is 10,000 = (100)2The largest 5-digit integer perfect square is 99,856 = (316)2So we want to know how many numbers that is, from 100 to 316 inclusive.It's 316 minus the first 99 = 217 of them.

Does 9 and 100 have anything in common?

Yes. They are numbers. They are real. They are rational. They are integers. They are positive. They are perfect squares. They are extrema of number with their digital length (9 is the biggest 1-digit number, 100 is the smallest 3-digit number). There are many more but that should keep you going for a while.


How many positive integers less than 2008 have an even number of divisors?

There are 1,963 such integers. Every factor of a number has a pair. The only time there will be an odd number of factors is if one factor is repeated, ie the number is a perfect square. So the question is really asking: how many positive integers less than 2008 (in the range 1 to 2007) are not perfect squares. √2007 = 44 and a bit (it lies between 44 and 45) So there are 44 integers less than (or equal to) 2007 which are perfect squares → 2007 - 44 = 1963 integers are not perfect squares in the range 1-2007 and have an even number of factors (divisors).


How many square numbers between 100 and 1000?

Infinitely many, since every positive number is a square of some other number. However, there are 21 perfect squares (SQUARES OF INTEGERS). From 112 to 312, inclusive.


What two square numbers total 21?

There is no pair of perfect squares that sums to 21. And the question is pointless if it is not about perfect squares because in that case there are infinitely many answers.There is no pair of perfect squares that sums to 21.
