Four of the zeros are significant... the two zeros after the digit 5 0 are simply 'place fillers'.

3 zeroes , the zeroes preceding before the number 40500 are all insignificant , whereas the 3 zeroes in the number 40500 are significant. Hence it is a number with 3 significant zeroes and 5 significant figures, i.e 40500
In the number 0.0040500, there are three significant zeros. Zeros appearing between non-zero digits (4 and 5) are significant. The zeros before the first non-zero digit (4) are not significant as they serve as placeholders. The zeros after the last non-zero digit (5) in the decimal portion are also significant.
in this number 5 digits are significant and 3 zeros are significant
According to Google!!
The rules for identifying significant figures when writing or interpreting numbers are as follows: 1. All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). 2. Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. 4. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
There are three significant figures: the trailing zeros are significant because they are indicative of the precision of the number.
Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing 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!
