The number with 21 zeros behind it is 10,000,000,000,000,000,000,000, which is also written as 10^21 in scientific notation. This number is obtained by multiplying 10 by itself 21 times. In mathematics, this number is referred to as a "sextillion."
The number 4,720,000,000,000,000,000,000 can be said as "four sextillion seven hundred twenty quintillion." In scientific notation, this number can be written as 4.72 x 10^21. The prefix "sextillion" indicates a number followed by 21 zeros, while "quintillion" indicates a number followed by 18 zeros.
any number containing 100 zeros has 100 zeros but i'm assuming you mean a 1 fallowed by 100 consecutive zeros; that is a Googol or 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
in my agenda at school, there is a little fact that the number centrillion, has 500 zeros. but, there is probaby a higher number out there. a googol is 1 followed by 100 zeros, but higher named number is a googolplex which is one followed by googol number of zeros - that's a lot of zeros!
The number 2,000,000,000,000,000,000,000 can be expressed in scientific notation as 2 x 10^21. This means that the number is a 2 followed by 21 zeros. In standard form, it is read as "two quintillion." It is a very large number that represents a quantity greater than two billion billion.
the number googol has exactly 100 zeros in it
septillion
sextillion
If the question is a number with a set of 8 zeros behind it, the answer is a hundred million. If the question is, as stated, 8 sets of zeros, the answer depends on how big each set is.
one decillion
a sextillion :) i feel clever knowing that
One hundred sextillion.
We're not sure which side is "behind" a number. A '1' with 100 zeros to the right ---> of it is called "1 googol".
2*1020 this is called 200quintillion a quintillion is a number with 18 zeros a sextillion is a number with 21 zeros your number has 20 zeros therefore it is not quite a sextillion yet.
number 1 followed by 21 zeros
in the million million billions
One sextillion.
The number with 62 zeros behind it is 10^62, which is read as "10 to the power of 62." This number is obtained by multiplying 10 by itself 62 times. In mathematical notation, it is represented as 1 followed by 62 zeros: 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.
