The square of any number greater than 10 (or less than -10) will be greater than 100.
Yes, if the number is less than '1'.Just the opposite, if the number is greater than '1'.

Let's list the requirements for the mystery number: One's digit more than the ten's digit. Composite number. Two digits. Even number. Is two less than a square. Now that we've listed the requirements, let's look for a place to "attack" the problem. The easiest is probably to look at squares since our mystery number is two less than a square. Here are the first few squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 and 121. Since our mystery number is 2 less than a square, let's go through that. -1, 2, 7, 23, 34, 47, 62, 79, 98, 119. Now we'll look at two things at once; we'll look only at the 2-digit numbers that are even. (We don't have to look at the "composite number issue" because every even number except 2 is composite since it can be divided by 2.) 34, 62, and 98. Now the number with the one's digit greater than the ten's digit - and there's only one of them: 34. The number 34 has a one's digit greater than the ten's digit, is composite, has two digits, is even, and is 2 less than a square.

2 digit number which is square number less than 42 but greater than 29 = 36square numbers are 2, 9, 16, 25, 36, 49,...
87 is the only 2-digit number that is 6 greater and 13 less than a square, but it is not prime.
something I don't know
The number must be 42.
The square of any number greater than 10 (or less than -10) will be greater than 100.
The number is 57.
Yes, if the number is less than '1'.Just the opposite, if the number is greater than '1'.
Work it out with a few clues. Only a 3 can be the last digit of number whose square has a 9 at the end. There are 4 digits in the square, so the root is greater than 31, and less than 100. The square of 5 = 25, so the square of 50 = 2500
9 is an odd square number less than 10 and 92 = 81 which is greater than 50
No, a 4-digit number is not always less than a 5-digit number. The value of a number is determined by the digits it contains, not the number of digits. For example, the 4-digit number 9999 is greater than the 5-digit number 1000. It is important to consider the actual numerical value when comparing numbers, not just the number of digits.
