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).
Therefore, it requires 10 94 such books to print all the zeros of a googolplex (that is, printing a googol zeros). [4] If each book had a mass of 100 grams, all of them would have a total mass of 10 93 kilograms. In comparison, Earth's mass is 5.97 × 10 24 kilograms, [5] the mass of the Milky Way galaxy is estimated at 1.8 × 10 42 kilograms ...
67,108,864 = 8192 2 = 4 13 = 2 26, number of primitive polynomials of degree 32 over GF(2) [14] 67,109,540 = Leyland number using 2 & 26 (2 26 + 26 2 ) 67,110,932 = number of 32-bead binary necklaces with beads of 2 colors where the colors may be swapped but turning over is not allowed [ 15 ]
This is generally used to denote powers of 10. Where n is positive, this indicates the number of zeros after the number, and where the n is negative, this indicates the number of decimal places before the number. As an example: 10 5 = 100,000 [1] 10 −5 = 0.00001 [2]
Alternatively, and for greater numbers, one may say for 1 ⁄ 2 "one over two", for 5 ⁄ 8 "five over eight", and so on. This "over" form is also widely used in mathematics. Fractions together with an integer are read as follows: 1 + 1 ⁄ 2 is "one and a half" 6 + 1 ⁄ 4 is "six and a quarter" 7 + 5 ⁄ 8 is "seven and five eighths"
For higher powers of ten, naming diverges. The Indian system uses names for every second power of ten: lakh (10 5), crore (10 7), arab (10 9), kharab (10 11), etc. In the two Western systems, long and short scales, there are names for every third power of ten. The short scale uses million (10 6), billion (10 9), trillion (10 12), etc.
A post shared on X claims that there were 10 million fewer voters in 2024 than in 2020. Verdict: False Votes are still being counted. The vote total will likely be more than 150 million votes.
The word crore derives from the Prakrit word kroḍi, which in turn comes from the Sanskrit koṭi (कोटि), [2] denoting ten million in the Indian number system, which has separate terms for most powers of ten from 10 0 up to 10 19. The crore is known by various regional names.
