The term ‘Googol’ is written in number form as number 1 followed by how many zeros?
Googol Googol A googol is the large number 10. In decimal notation, it is written as the digit 1 followed by one hundred zeroes: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. The term was coined in 1920 by 9-year-old Milton Sirotta (1911–1981), nephew of U.S. mathematician Edward Kasner. Kasner popularized the concept in his 1940 book "Mathematics and the Imagination". Other names for googol include ten duotrigintillion on the short scale, ten thousand sexdecillion on the long scale, or ten sexdecilliard on the Peletier long scale. A googol has no special significance in mathematics. However, it is useful when comparing with other very large quantities such as
Perfect number 1) with odd prime "p" and, in fact, with all numbers of the form 2(2 − 1) for odd integer (not necessarily prime) "m". Owing to their form, 2(2 − 1), every even perfect number is represented in binary form as "p" ones followed by "p" − 1 zeros; for example, and Thus every even perfect number is a pernicious number. Note that every even perfect number is also a practical number (c.f. Related concepts). It is unknown whether there is any odd perfect number, though various results have been obtained. In 1496, Jacques Lefèvre stated that Euclid's rule gives
