Okay, in this problem, we're going to figure out which of these numbers, if any, are solutions to this equation.
00:09
So let's do part a.
00:10
We have a natural log of two times one -half times negative three plus natural log of 5 .8 plus three.
00:23
Let's make sure i have my parentheses correct there.
00:27
Okay, and so let's simplify that.
00:30
There's a lot of simplifying we can do there.
00:32
First of all, we can simplify the two times one half.
00:36
That's just one.
00:38
And now we have the natural log of negative 3 plus natural log of 5 .8 plus 3.
00:44
And we can simplify the minus 3 plus 3.
00:46
Add those together and you get 0.
00:48
We have the natural log of the natural log of 5 .8.
00:51
Natural log doesn't cancel natural log, so this is not 5 .8.
00:55
And so this one is a no.
00:57
We did not have a solution...
