Prime number between 196 and 289 whose digits add to 14?
Possibles 239, 248, 257, 266, 275, 284.
248, 266 and 284 are multiples of 2, 275 is a multiple of 5.
This leaves 239 and 257.
Only 239 has one digit which is the square of another.
So there you have it.
Integers of 6 digits are normally greater than integers of 5 digits
The first squared number that is a multiple of 10 is three digits.
Any 5-digit number is greater than a 4-digit one.
Not necessarily. Consider 444. The digits are not different. The first and second digits are not multiples of 3 The first digit is not greater than the second digit. In spite of all that, 444 is a 3-digit number
Ummm... If I am correctly interpreting the question to be asking for a prime number less than 19, whose digits added together are greater than 7, then the answer is 17. There really aren't many options here (1, 2, 3, 5, 7, 11, 13, 17), only three of which even have multiple digits (11, 13, 17). So... 177. qed?
It is greater because with more digits the greater the value of the number will be.
which is greater, whole number with 5 digits or the whole number with 6 digits?
Integers of 6 digits are normally greater than integers of 5 digits
The least whole number with 6 digits is greater because it has more digits than 5 digits.
11 squared is 121
The first squared number that is a multiple of 10 is three digits.
It's the number that has more digits to the left of the decimal point (if there is no decimal point, it's the number with more digits). If the number of digits to the left of the decimal point is the same, find the position farthest to the left where the digits are different. The number with the greater of those two digits is the greater number. For example, 10000 is greater than 9999 because 10000 has more digits, and 6350 is greater than 6349 because the farthest-left position that is different is the tens place, and 5 is greater than 4.
Zero!

The mystery number is 155. When rounded to the nearest hundred, it rounds to 200. The sum of its digits is 1+5+5=11 which is greater than 10, so we must adjust the digit in the hundreds place. When rounded to the nearest ten, 155 rounds to 160, which has digits summing up to 1+6+0=7.
The greatest whole number with 5 digits is 99,999. The next greater whole number is 100,000, which is the least whole number having 6 digits.
