Simplify (– log7 24 - log7 4 - log7 3)?

The negative sign at the start throws me off... Also, each 7 should be the base of the log.

-log_7(24) - log_7(4) - log_7(3)
= -log_7(24 * 4 * 3)
= -log_7(288)
= -log_7(24 * 4 * 3)
= -log_7(288)

Let log be log to base 7
- (log 24 + log 4 + log 3)
- log 288
- 2.9102
- (log 24 + log 4 + log 3)
- log 288
- 2.9102
