Take a look at this link. It does a good job of explaining why the significant figure rules are the way they are. However, I cannot say that these rules are "official" since they are not on the Official Science Olympiad website.SWAnG wrote:Thanks!

**Significant Figure Rules for Logarithms:**When you take the log of a number with

**N significant figures**, the result should have

**N decimal places**. The number in front of the decimal place indicates only the order of magnitude. It is not a significant figure.

**Significant Figure Rules for Exponents:**When raising 10 to a power: If the power of 10 has

**N decimal places**, the result should have

**N significant figures**. The rule for raising e to a power is similar.
