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:
Giga-. Giga- ( / ˈɡɪɡə / or / ˈdʒɪɡə /) is a unit prefix in the metric system denoting a factor of a short-scale billion or long-scale milliard (10 9 or 1,000,000,000 ). It has the symbol G . Giga- is derived from the Greek word γίγας ( gígas ), meaning "giant". The Oxford English Dictionary reports the earliest written use of ...
Billion. Billion is a word for a large number, and it has two distinct definitions: 1,000,000,000, i.e. one thousand million, or 10 9 (ten to the ninth power ), as defined on the short scale. This is now the most common sense of the word in all varieties of English; it has long been established in American English and has since become common in ...
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. In comparison, Earth's mass is 5.972 × 10 24 kilograms, the mass of the Milky Way galaxy is estimated at 2.5 × 10 42 kilograms, and the ...
A nanosecond (ns) is a unit of time in the International System of Units (SI) equal to one billionth of a second, that is, 1⁄1 000 000 000 of a second, or 10 −9 seconds. The term combines the SI prefix nano- indicating a 1 billionth submultiple of an SI unit (e.g. nanogram, nanometre, etc.) and second, the primary unit of time in the SI.
Therefore, a long scale n-illion equals 10 6n. [1] [2] In some languages, the long scale uses additional names for the intermediate multipliers, replacing the ending -ion with -iard; for example, the next multiplier after million is milliard (10 9); after a billion it is billiard (10 15). Hence, a long scale n-iard equals 10 6n+3.
(10 9 days is roughly 2.738 million years.) About 10 9 months ago, dinosaurs walked the Earth during the late Cretaceous. (10 9 months is roughly 83.3 million years.) About 10 9 years—a gigaannus—ago, the first multicellular eukaryotes appeared on Earth. About 10 9 decades ago, the thin disk of the Milky Way started to form. (10 9 decades ...
n ! {\displaystyle n!} In mathematics, the factorial of a non-negative integer , denoted by , is the product of all positive integers less than or equal to . The factorial of also equals the product of with the next smaller factorial: For example, The value of 0! is 1, according to the convention for an empty product.
