Okay, here i want to find x.
00:02
First step is to get the logs all on one side.
00:06
So i have log of x plus 5 plus log of x minus 2 equals 2.
00:16
And then by the first law of logs, you have log a plus log b.
00:21
It's simply log of a times b.
00:24
So x plus 5 times x minus 2.
00:28
Now, if you have log with no base number written there, it always means base 10.
00:34
So i know here is base 10.
00:37
And then if i have log base a of b equals c, that means a the base to power c after equal b.
00:49
That's the conversion from log to power form.
00:53
So here then what we have is 10 is the base, the power is 2, it will be x, and the base...
