Answer:
Step-by-step explanation:
I'm going to have to assume that you meant "log "a*(30a)^3".
If that's the case, then applying the multiplication rule of logs produces:
log a + log (30a)^3, which in turn comes out to:
log a + 3*log (30a), or
log a + 3*(log 30 + log a), or
log a + 3*log a + 3*log 30
This simplifies to:
4*log a + 3*log 30
