Yes, I do.

What do you want to do from there?

I want to move log2 to the right handside

We already have a log(2) on the RHS.

Then multiplying 3x through.

That will not do anything to help. You can not cancel the 3x in the denominator.

Then taking antilog, will tha help?

I have no idea what you want to do. I guess I have got jumbled up.

No don't. What I have said so far is what the book used to solve similar ones. Please, then help me

I would but I do not know what you want to do. Let's start at the beginning maybe?

Ok,
x^2 + 2 = 3x
x^2 - 3x + 2 = taking log
Log(x^2/3x) + log2 = o
This is how I would solve it.

Hi;
If we are starting with a quadratic
do we really need logs to solve it?

In fact I factorised it and had 1 or 2 as answers. But since you suggested that log should be used so I agreed. Actually, wanted to learn more of log that is why I did not tell you that I have factorised

Forget about the use of a log on this one. The factoring you have done is fine.

Please if you wouldn't mind use log to solve it completely, and let me see how you would have solve it by using log, please!

I do not if it can be solved by a log but give me some time.

Ok, I get you, thank you!

If we now take the log of both sides we can do the right side but not the left. I would say it can not be done using logs.

How about if the 3x had been x^2? Could one use log?

You would then have x^2 -x^2 +2 = 0 which is not even an equation.

Errr, ok, I see. I have another, but maybe tommorow or today would post it.

Take a break if you need it. Or if you are feeling refreshed then post it.

Find X;
Log(3x - 1) - log2 = 3
That is it.
