If you must use a calculator (rather than the simpler

**definition**of logs), then you'll need to use the**change-of-base**formula to convert the base-two log to either a base-10 or base-e log.

...where "b" is the original base and "a" is the base you're changing to.

(The answer will be the same, regardless of the base you choose. But you have to use a base that your calculator can understand.)
