Evaluate the expression.
log3 15 − log3 30 + log3 486
i gotten to the part where log3 243.. and im stuck after that

Yes, that will give you: log%283%2C243%29, and log%283%2C243%29 = highlight_green%285%29 (computer, or calculator-calculated),

OR

log%283%2C243%29 ------ 3%5Ex+=+243 ----- 3%5Ex+=+3%5E5

As the bases are equal, so are their exponents. Therefore, log%283%2C243%29 = highlight_green%285%29

You can do a check by calculating the original problem: log%283%2C15%29+-+log%283%2C30%29+%2B+log%283%2C486%29, which will give you: 5.
