Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

2 x 2 x 2 = 8
2 x 2 x 3 = 12
2 x 3 x 3 = 18
2 x 2 x 5 = 20

How do you calculate all factors of 756?
Once you find the prime factorization, every other factor can be found. Don't forget 1.
2 x 2 x 3 x 3 x 3 x 7 = 756
1,2,3,7
4,6,14 (2x2, 2x3, 2x7)
9,21 (3x3, 3x7)
12,18 (2x2x3, 2x3x3)
27 (3x3x3)
That's half of them. The rest can be found by dividing them into 756.

It is a tautology. All whole numbers are integers and all integers are whole numbers.
What are the prime numbers less than 100 that can be written as a sum of two squars?
The primes less than 100 that can be represented as a sum of two squares are
2,5,13,17,29,37,41,53,61,73,89,97. And here is the actual sums I used to get those primes.
1+1 = 2
4+1 = 5
4+9 = 13
16+1 = 17
4+25 = 29
36+1 = 37
16+25 = 41
49+4 = 53
36+25 = 61
64 +9 = 73
64+25 = 89
81+16 = 97
No.
Is it possible to find the prime factorization of a negative number?
No. Any factor string of a negative number would have to include at least one negative number and there aren't any negative prime numbers.

Does 63 have the fewest prime number?
63 does not have fewest prime factors. It is a product of 3, 3 and 7.
How you show one-fifth on your computer?
You can write this as 1/5. To actually have one number on top of the other, the best option is to use an equation editor, if you happen to use a program that supports that.

What is the twenty seventh power of an imaginary number?
See the Wikipedia article on Imaginary Numbers. i^n = i^(n mod 4). With n = 27, 27 mod 4 = 3, and i^3 = -i. This is easier to visualize when you consider the graphical representation of complex numbers, and use polar coordinates. Writing i as exp(i*pi/2), (from Euler's formula), then i^27 = {using exp() to mean the natural base e, raised to a power} exp(i*pi/2)^27 = exp(27*i*pi/2) = exp(13.5*i*pi) = exp((12 + 1.5)*(i*pi)) = exp(12*i*pi)*exp(3*i*pi/2).
Since the coefficient of i in the exponent is an angle (in radians), then even multiples of pi are the same angle as 0 {exp(0) = 1} so we are back to the same as exp(3*i*pi/2), which is pointing straight down [-i]. Note that 3*pi/2 radians is the same as 270°.
Since the question asked about 27th power of an imaginary number, that could mean a multiple of i, such as bi, where b is any real number. In this case, you would have (bi)^27 = (b^27)(i^27) = (b^27)(-i). So if b = 1.5 for example, then you would have (-i)(1.5^27) ≅ -56815i.
