  2. Power of 10 - Wikipedia

    en.wikipedia.org/wiki/Power_of_10

    Power of 10. Visualisation of powers of 10 from one to 1 trillion. A power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ten are:

  3. Googolplex - Wikipedia

    en.wikipedia.org/wiki/Googolplex

    A typical book can be printed with 10 6 zeros (around 400 pages with 50 lines per page and 50 zeros per line). Therefore, it requires 10 94 such books to print all the zeros of a googolplex (that is, printing a googol zeros). If each book had a mass of 100 grams, all of them would have a total mass of 10 93 kilograms.

  4. Repeating decimal - Wikipedia

    If 10 is a primitive root modulo p, then the repetend length is equal to p − 1; if not, then the repetend length is a factor of p − 1. This result can be deduced from Fermat's little theorem, which states that 10 p−1 ≡ 1 (mod p). The base-10 digital root of the repetend of the reciprocal of any prime number greater than 5 is 9. [8]

  5. Zero of a function - Wikipedia

    en.wikipedia.org/wiki/Zero_of_a_function

    A "zero" of a function is thus an input value that produces an output of 0. [ 2] A root of a polynomial is a zero of the corresponding polynomial function. [ 1] The fundamental theorem of algebra shows that any non-zero polynomial has a number of roots at most equal to its degree, and that the number of roots and the degree are equal when one ...

    In number theory, Skewes's number is any of several large numbers used by the South African mathematician Stanley Skewes as upper bounds for the smallest natural number for which. π x li x. where π is the prime-counting function and li is the logarithmic integral function. Skewes's number is much larger, but it is now known that there is a ...

  7. Googol - Wikipedia

    en.wikipedia.org/wiki/Googol

    To put in perspective the size of a googol, the mass of an electron, just under 10 −30 kg, can be compared to the mass of the visible universe, estimated at between 10 50 and 10 60 kg. [5] It is a ratio in the order of about 10 80 to 10 90 , or at most one ten-billionth of a googol (0.00000001% of a googol).

  8. Trailing zero - Wikipedia

    zeros. If n < 5, the inequality is satisfied by k = 0; in that case the sum is empty, giving the answer 0. The formula actually counts the number of factors 5 in n!, but since there are at least as many factors 2, this is equivalent to the number of factors 10, each of which gives one more trailing zero. Defining

  9. Talk:Googolplex - Wikipedia

    en.wikipedia.org/wiki/Talk:Googolplex

    To write googolplex you need to write a "1" followed by 10^100 zeros. So you really need 10^100 "boxes" to write the number itself. And as you said, there are ~10^183 Planck spaces in the universe, assuming we can somehow "write" a zero in each of them, we would be able to write Googolplex.
