So to solve this equation, we need to get to the x in here.
00:06
So we need to have, at the very end, we want x equals some junk, whatever.
00:14
So the main thing that's stopping us is these natural logs, which we know we can do, undo with exponentials.
00:22
But the first thing we need to do is deal with this minus sign.
00:24
And luckily, we have a nice log property that it, whenever subtracting logs is the same thing as dividing the arguments.
00:33
So the arguments are what's inside the parentheses.
00:37
And this just comes from the fact that it's undoing exponents, because exponents turn multiplication into addition, so logs turn addition into, uh, to turn subtraction into divisions...
