Okay, whoever said that a number can only have an even number of factors IS Wrong Take a prime number and square it. If you square a prime number, the number you get will only have 3 factors. For example, if I squared the number 3, I would get 9. 9 only has three factors: 9, 3, 1 Any prime number squared has Three factors.
well, i believe it goes like this (not certain) 25 is the only not prime number so... 3xcubed x squared -5 squared
No because the number is being squared, not multiplied by its inverse. An identity property is only when a number is multiplied by its inverse.
1 is the numerical coefficient if no other numeral is shown.
As we are only just into the 21st century it is most unlikely.
Only time will tell.
The Yankees won the World Series in 2009. It is currently their only championship in the 21st century.
As we are only 11 years into the 21st century, it is too soon to predict.
The 21st Century customer has a wealth of information available to them readily. They do not have to depend on the company or mass media as their only source of information on purchase decisions. The 21st century customer has more opportunities for substitute products and is not brand loyal.
No, The band only has a play for American Idoit
Only if it's being used as an adjective.
Only 2."whip my hair" and "21st century girl"
A prime number is only divisible by itself and 1... A squared number is a multiple of itself - and thus is not a prime number !

only if the first number is 4 (16 when squared) and the second is 3 (9 when squared)
There are two answers to your question: 1st) The Earth is more than 6000 years old (but that's not important to your question). 2nd) The 21st century refers to the time after the accepted year zero (A.C.E, or after the common era). So right now, we are in the 21st century (21st set of 100-years) after year zero.
