Okay, so we want to solve the following, or compress it into a single log.
00:05
Well, let's first note that we have for part a, a3, and a 2.
00:09
So let's use our power rule to bring that back up.
00:12
Let's just write that out again.
00:16
So we get negative log of x plus 4 to the power of 3 and plus log base 10 of x to the power of 2.
00:24
And now we can use both our, since we have a minus sign, our quotient rule and our plus sign here.
00:30
So that's a product rule.
00:32
So let's look at our first two terms and use our quotient rule.
00:38
Well, let's recall that x squared minus 16 is the difference of two squares...
