How many significant digits are in each of the following numbers?
A. 4 B. 1 C. 5 D. 2 E. 4 F. 3 Remember the rules: A. zeros are only counted after other numbers if they extend past the decimal B. in this case the zeros are not counted becuase they do not extend past the decimals. Sometimes to indicate that these zeros should be counted a number like this may be written as 7000. where there is a decimal with no numbers afterwards. C. Zeros are also counted when sandwiched between numbers (in other words when numbers are on both sides of the zero(s). This means the 2, 5, 0, 9, and 5 are all counted. D. only the 49 are counted becuase these zeros come before the numbers, not after E. with scientific notation, only consider the number on the left for sig digs. The multipyler is not counted. D. same thing.
