What number is a 1 followed by 100 zeroes?
Googolplex Googolplex A googolplex is the number 10, or equivalently, 10. Written out in ordinary decimal notation, it is 1 followed by 10 zeroes, that is, a 1 followed by a googol zeroes. In 1920, Edward Kasner's nine-year-old nephew, Milton Sirotta, coined the term "googol", which is 10, then proposed the further term "googolplex" to be "one, followed by writing zeroes until you get tired". Kasner decided to adopt a more formal definition because "different people get tired at different times and it would never do to have Carnera a better mathematician than Dr. Einstein, simply because he had more endurance
Kynea number is (30+1) − 2. Kynea number A Kynea number is an integer of the form An equivalent formula is This indicates that a Kynea number is the "n"th power of 4 plus the ("n" + 1)th Mersenne number. Kynea numbers were studied by Cletus Emmanuel who named them after a baby girl. The sequence of Kynea numbers starts with: The binary representation of the "n"th Kynea number is a single leading one, followed by "n" - 1 consecutive zeroes, followed by "n" + 1 consecutive ones, or to put it algebraically: So, for example, 23 is 10111 in binary, 79
