I forgot all about logarithms. Not sure how to start.

Thanks

[green tangle]

First start with factoring out 7 on the lefts side and try to remove x-2

[true junco]

I see

[green tangle]

This is obviously a trap but do it and you will see that we will be missing one answer

[true junco]

How so

I haven’t done logarithms in a long time

[green tangle]

Ok np

You know that you can remove x-2 from both sides right?

[true junco]

Right

[green tangle]

Ok

Let me send an example

You should know some stuff before we start

Do you remember this?

(Natural log)

[true junco]

Somewhat

[green tangle]

Also there is this rule

[true junco]

I remember that

[green tangle]

Good

Now please take a look at the way the question below is solved

[true junco]

I see

But how would we lose an answer

[green tangle]

Because we remove x-2

And not paying attention that x could equal 2

You can't divide by 0

If you plug in 2 you will see, one of the answers is 2

Before simplifying it ofc

[true junco]

I see

[green tangle]

Yes, always remember that cuz I have lost alot points on not paying attention to that

Ok now we removed it and we are left with a very simple equation similar to the one I sent here

[green tangle]

This

[true junco]

ln(7)=10x+6

Right?

[green tangle]

Yes exactly

[true junco]

I hate logarithms

[green tangle]

Why they cam be really useful

Can*

[true junco]

Only because im weak in that area

Ill need alot of practice

I regret cheating all through my logarithms class

[green tangle]

Well, I have tons of log questions

If you want I can send them to you

[true junco]

Thatd be nice

[green tangle]

I will DM you rn and I will send them later cuz I have to go to sleep rn
