What prime numbers have a 0 in them?
An infinite number of prime numbers contain one or more zeroes, though a prime number, always being odd, cannot end in a zero. The first four prime numbers containing zeroes are 101, 103, 107 and 109.
Number one followed by 27 zeroes?
1x1027 is often known as octillion, it being 103(8+1), giving the 8 which provides the 'oct-' prefix.
What digits are considered significant in a measurement?
Non-zero digits are always significant. Thus, 569 has three significant digits, and 69.35 has four significant digits. Zeros are sometimes significant and sometimes aren't: # Zeroes placed before other digits are not significant; 0.0968 has three significant digits. # Zeroes placed between other digits are always significant; 70063 kg has five significant digits. # Zeroes placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. # Zeroes at the end of a number are significant only if they are behind a decimal point as in (c). Otherwise, it is impossible to tell if they are significant. For example, in the number 8200, it is not clear if the zeroes are significant or not. The number of significant digits in 8200 is at least two, but could be three or four. To avoid uncertainty, use scientific notation to place significant zeroes behind a decimal point: 8.200 * 103 has four significant digits 8.20 * 103 has three significant digits 8.2 * 103 has two significant digits
How many significant digits are in the number 605.20?
5 (zeroes before the number don't count, zeroes after the number do)
How many zeroes in 175 million?
There are 6 zeroes in the number 175,000,000.
What is the scientific notation of 4500?
4.5 X 103 The zeroes are superfluous.

A number with 72 zeros is called?
We can figure this out by writing said number out, or dividing it's exponent in exponential/scientific notation to find how many pairs of zeros that is. So 72/3 = 24 pairs of 3 zeros. We then write out 24 zeros as placeholders and count up in reverse by each decimal place, giving a number above million a name based on how far it is from the hundreds place. So we will do this: 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 where a 0 is a placeholder for 3 zeros and count them backwards until we reach one, naming each number by a combination of latin names. So hundred, thousand, million, billion, trillion, quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion, undecillion, duodecillion, tredecillion, quattuordecillion, quindecillion, sexdecillion, septendecillion, octodecillion, novemdecillion, vigintillion, unvigintillion, duovigintillion. There are 24 of those when you count, adding up to 24 pairs of 3 zeros. And if you pay attention to the fact that there are 24, and we counted up in the latin naming system to what would be 22 with viginti- meaning 20 and duo just meaning 2, we can make a guess as to whatever the number name is by subtracting 2 from the number of pairs of zero. Say we want to find what a number is with 96 zeros. We take 96/3, which is 32, and with the naming system we use triginti for 30 and duo for 2, so that would be duo- triginti - illion or duotrigintillion. Take note that since we are using latin based numbers, they will be flipped from what english users are used to. Thirty two will take the form two thirty if we use the same system as in latin. The 10s place will be said 2nd. Now what if we have an odd number of zeros? That usually means we have a number that has, say 10 in the first group when we group by 3 zeros. This will change it because instead of, say a number with 96 zeros, we can have a number with 97 zeros. In this case we just need to take that zero out of the number to make it easier to name. So we take that single 0 out of the number so it will have 96 zeros, an even number which we can divide by 3. Then we name it and put that zero back to the original first digits and we say that number then the latin name we figured out. So that would be, say, thirty duotrigintillion or we can take it up another step where we have 98 zeros, and since 98 isn't nicely divisible by 3, we just subtract until we get one that is divisible by 3 and add that remaining value to the first number again. That would be, for example, 300 duotrigintillion. There are resources online, such as the big numbers wiki, that can help you learn this system if I did not explain that very well
What is the rule for multiplying by a positive power of 10?
To multiply by a positive power of ten, just add the number of zeroes as the number of the exponent. For example, if you have 103 which is 10 times 10 times 10, you will get 1,000. Hope this helps!
What is the difference of a googol and a googolplex?
A googol is the number 1 followed by one hundred zeroes, and a googolplex is the number 1 followed by a googol zeroes. A googolplexplex is the number 1 followed by a googolplex zeroes, and so on.
What number is googel?
Google is a number with 100 zeroes

How many zeroes are in a sexdecillion?
The number sexdecillion is written 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, or 1 followed by 51 zeroes.
