It's been decades since I've attended college and am a retired engineer; however, I like to stay in practice doing math. So as I do with other videos of yours that interest me, I solve them before watching your solution just to see if our methods match. I still have the same problem now that I had in HS viz. I do some of the steps in my head and not write them down thus partial credit. Other than that we both essentially use the same methods. It's good to know that I haven't forgotten much over time. Great videos, btw.
I as well. The difference is that I am a musician and artist who loved math. In my 70s, this you tube math keeps my brain in shape. But as in College, I work it out in my brain before I put it on paper. Thank you for ll the problems you post Table Class Math.....Love it!
Greetings . The solution for X is (Ln10-1)/2. We arrived at the solution as follows, e^2X+1 -8=2 is equal to e^2X+1=2+8=10 and Ln e^2X+1= Ln 10. Now, (2X+1)Ln e =Ln 10, and 2X +1=Ln 10. Moving on, 2X=Ln 10-1, and X= (Ln 10 -1)2.
@ 9:09, easily simplified to 1/log 2. log 10 = 1. (basic rule: log base a of a = 1 and log w/o a base written is base 10). Odd that he does this simplification for ln (e) later in the video (ln = log base e) but not here.
What if you don’t have a calculator Ike some of us back in the60’s. It will be helpful if you explain how to use log tables if they still teach mathematical principles
It's an inverse of the exponent. If I do ln(3), it's asking "What power do I raise e to to get 3?". The reason that ln(e) is 1 is because we're asking "what power do I raise e to to get e?", and that's 1.
Bro, I like your videos but usually have to fast forward through most of them because you take too long to get to the point! This video could've been edited down to about 3 or 4 minutes.
Stop smiley faces, please. Folks who watch do so because they want to improve understanding of algebra, not caricatures! Love what you teach not how you teach maybe I should unsubscribe.

Although I learned all of this at school, then maths courses at university, I wish, now retired, Id been taught more about finances and investments!

Thank you for a fantastic analysis and explanation of solving Exponential equation on a step by step basis.
Great explanation
Happy Birthday Devil Dog!! Great work.

Iv it .Thanks 4 makin me understand
e^2X+ 1 (e2^3= 8 (8÷4)= 2
a lil confused, is log inverse of exponent or is it square root?
It's an inverse of the exponent. If I do ln(3), it's asking "What power do I raise e to to get 3?". The reason that ln(e) is 1 is because we're asking "what power do I raise e to to get e?", and that's 1.
e^(2x+1)-8=2
E^(2x+1)=10
Log(e)10=2x+1
And I don't know where to go from there. lol
Cheers dude, it’s my birthday tomorrow 😏
Happy dead day
Helpful
I get X= .6513
Sorry this is not a explanation of exponential equation ! In order to understand this You have to explain what log means!
I cannot take notes. So, I record my classes. Then I review and make notes from the recording.
mm kay? mm kay?
Hell

Too gabby
Why not concentrate on solving ?
e is not a variable.
who said it was
He very surely mentioned that. Of course, it probably got lost in all the tangents he goes into.
