Zero is considered a significant digit when it is to the left or the right of the decimal point. It is also a significant digit when it follows a non-zero digit or when it is between two digits.
All nonzero numbers are significant.
Three: 502. Leading and trailing zeroes are not significant (but the zero between two nonzero numbers is).
Move 6 decimal places to the right from the starting decimal position to get: 7.65 x 10-6. Note that the exponent for base 10 is negative because the leading nonzero digit takes place after the decimal point!
Move 6 decimal places from the starting point to get 5.6 x 10-6. We obtain the negative exponent due to the leading nonzero digit 5 in the millionths place.
0.70010 in scientific notation is 7.001 x 10^-1
All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.
All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.
All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.
Five. Zeros that are after the decimal and are after nonzero integers are always significant.
three if somebody goes through the bother of putting extra zero after a decimal point then it must be because they are significant. 0.00030000000000000 has 14 significant figures 0.000000000000000000000000000000000000000000004 has only one significant figure
Four - all nonzero digits are significant. * * * * * Not only that, but embeded 0s are also significant as are 0s after the decimal point.
There are four significant figures in 15.50. All nonzero digits are significant, and the trailing zero is significant because it comes after a decimal point.
All zeros appearing in a number without a decimal point and to the right of the last nonzero digit are not significant unless indicated by a bar. Example: '1300' has two significant figures: 1 and 3. The zeros are not considered significant because they don't have a bar. However, 1300.0 has five significant figures. So 10200 has 3 significant figures because it does not have a decimal point so the zeros after the 2 are not considered significant.
All nonzero numbers are significant (1, 3, and 7 are significant). Zeros in-between significant digits are significant (the first zero is significant). All zeros after the decimal point that aren't placeholders are significant (last zero is significant).
1. Zeros appearing between nonzero numbers are significant. For example, 3.02 has 3 significant figures. 2. Zeros appearing in front of nonzero numbers are not significant. For example, 0.0009 has 1 significant figure. 3. Zeros at the end of a number and to the right of a decimal point are significant. For example, 26.600 has 5 significant figures. 4. Zeros at the end of a number and to the left of a decimal point can be either significant or not significant. If the zero has been measured or estimated, it is significant. It is not significant if it has not been measured or estimated and is merely serving as a placeholder. A decimal placed after the zeros indicates that the zeros are significant. For example, 2000. has 4 significant figures. 2000 (with no decimal) has one significant figure. 5. In scientific notation, all digits appearing before the exponent are significant. For example, 3.226 x 105 has 4 significant figures.
All nonzero numbers are significant.
Rules for determining significant figures1. All nonzero digits are significant.2. All zeroes between nonzero digits are significant.3. Zeroes to the right of a nonzero digit, but to the left of an understooddecimal point, are not significant.If such zeroes are known to have been measured, however, they aresignificant and should be specified as such by inserting a decimal point to theright of the last zero.4. In numbers less than one, zeroes to the right of a decimal point that areto the left of the first nonzero digit are never significant.They are simply placeholders.5. In numbers less than one, the zero to the left of the decimal point isnever significant.6. All zeroes to the right of a decimal point and to the right of a nonzerodigit are significant.
