2, 3, 7, 8
Hint, but not your answer: You know your answer has to be between 11 and 99. Furthermore, it has to be a square. One, two, and three when squared are still single digit numbers. Four squared is 16, which is not squaring the ones digit. Keep going...
Yes it is a real number. Real numbers exist on a number line, so it doesn't matter big they are, they will always fit. Complex numbers on the other hand will never have a place on that number line.
That depends entirely on why it was squared in the first place, and why you would wish to square it the second time.
there are infinity of those, because numbers never end.
A decimal number is one way of representing numbers where each place for a digit has a place value that is ten times that of the place to its right. Most all the numbers that you familiar with (judging from your question) will be decimal numbers. A decimal number need not be a [decimal] fraction.
Individual digits within a number have place values, not whole numbers.
i dont nowok
67 is not a even number as 7 is at its unit place. Numbers which have 0,2,4,6,8 etc. on its unit place are even numbers. For example= 2,42,52,64,76 etc.
3897
numbers never end, so it's impossible to say what the highest number is. I'm not sure that we even have names for all the place values yet. :D (10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000) haha, is there a place value for that i wonder???
19,29,59,79,89 are the prime numbers with 9 in its Unit place.
Numbers between zero and nine are represented by 1-digit numbers -- 8, for example. Numbers between ten and ninety-nine are represented by 2-digit numbers -- 58, for example. Numbers between one hundred and nine-hundred-ninety-nine are represented by 3-digit numbers -- 258, for example.Look at the number 258. The last digit on the right is in the ones' place. The number 258 contains 8 ones.The next digit to the left is in the tens' place. The value of a number in the tens' place is ten times the value of the same number in the ones' place. The number 258, therefore, contains 5 groups of ten.The next number to the left is in the hundreds' place. The value of a number in the hundreds' place is ten times the value of the same number in the tens' place. The number 258, therefore, contains 2 groups of one hundred
