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.
Without actually multiplying, you would have to estimate the zeroes as 2.122 = 12,269,432.738610566 10022 = 1044 [ (102)22 ] So there would be between 22 and 35 zeroes including the significant figures. * 21022 is about 1.2269432738610566 x 1051 ---
