Example Solving Algebraic Equation Using Logarithmic Properties, Logarithms Lesson 13

[@maxnilsson8726]

This playlist might just have saved my grade. Thanks man. Not all heroes wear capes

[@spiralanimal3849]

Went from knowing little to nothing about log to knowing everything, thank you for the lessons

[@bluedressable]

My teacher decided that logarithms were not important to teach, and when the EOC Exam came around, about 50% of the questions were on logarithms... By the grace of God, I passed the exam, now that I'm going into college, I am more confident now that I understand these. Thank you so much for making these video series Paul! :)

[@jarrettspence6998]

This video helped me so much!!!!!!!!!!!!!!! If it wasn't for this video, i wouldn't have known how to do this type of logarithm which i have been struggling with for a while. Thank you so much.

[@syedahmed883]

dude these are the best tutorials.....thnx alot........god bless u

[@dilshadjumat4441]

i finally understand on how to do the logarithms.Thank you so much , your tutorial is very useful .

[@learnmathtutorials]

The change of base formula is useful whenever you want to check the value of a logarithm on a calculator. Most calculators only come with a log base 10 button (LOG) and a log base e button (LN). The change of base formula lets you calculate any base with either one of these buttons. For further detail on using the change of base formula, please see Lesson 4 of this playlist.

Thank you very much Paul! I have a big math test coming up tomorrow and I was super nervous but now I understand all the concepts! So So So Helpful!

[@andrewmamusic2634]

Really enjoyed your explanation of logs. Thanks so much, Paul!

[@abhishekbhattacharjee4639]

wow! I effectively know the basics of log, an important part of mathematics ... thanks Paul.

[@needarandomname4330]

This last video was definitely needed thanks!

[@daneildavis5223]

i do think all 13 vidz are worth it. thanx for the help

[@balikakamble1433]

thank you sir for all these videos. these are so useful. thank you once again.

[@needarandomname4330]

I see some people are thanking you in Arabic so I'm tempted to say: ありがとうございます！

[@avibramh]

Thank you that help me شكراً

how do i expand log with a lower 2 [16x^4(cube root of x-8) over 7(x+15)^4

[@rudygarcia6689]

i'm stuck on a problem that has pi ^1-8x=e^9x. do you have a video on this type of problem? I would really appreciate it. Thank you. Rudy

[@alvincastro3405]

thank again sir

[@tutorialstube9587]

Hi Paul, this tutorial is excellent. Thank you very much. I have a question, how to solve this issue? For this statement to be true, what is the value of n? log2(n) < n or : n < (2^n)

[@jadebrown7206]

3 + log2(X) = log2(5) 3 = log2(5) - log2(X) 3 = log2(5/X) 2^3 = 5/X X = 5/8 I'm sorry but I still don't understand why you wouldn't just do what i have done above.

[@mohithrgowda8682]

answer is correct

[@crucialmaniac1016]

It is easy but there is no harm in knowing one more way to solve this

[@1118Tiffany]

thank you :)

[@chjethan2537]

Hi, Can you explain how is it calculated for log(2) without a calculator. On executing this on calculator we get 0.301029996... how can we get this on piece of paper. Thanks in Advance!

[@rachelosullivan6880]

Why and how did you choose to use 2 as your base number ie 2^(3+log2(x)) = 2^(log2(5)) ?

[@adikrah]

I think he chose 2 because, in both sides "log" has a base of 2

[@rachelosullivan6880]

thanks!

[@adikrah]

no prob

[@needarandomname4330]

Ok I have a problem: What if I wanted to make X the subject of the formula of 5^(3x-2) =7^(x+2) ?

[@VivzStudioSs]

You take the log base 5 of both sides to get the X out of the exponent and then use simple algebra.

how to calculate - log 2.3?

[@gamingmode6923]

use calculator

[@shan4diff13]

how to solve log base 3 of 5.

[@BhaswataChoudhury-e2e]

log base 3 of 5 = log base 10 of 5 divided by log base 10 of 3, plug that in your calculator and you'll have your answer

[@AT-hr3fw]

Sir, I would really appreciate if u could make a vid on proving an algorithm!! i.e LHS=RHS for eg: log x/y-z=log y/z-x=log z/x-y ,show that xyz=1 Thank you.

[@sanjaywani1367]

how to find x=3 power3 log base 3 2

[@khatarnakgamer2738]

how to solve this one please help ? 2log10(5) + log10(8)-1/2 log10(4)=0 which one is currect ? a)2 b)4 c)2+2log10(2) d)4-4log10(2) pls help soon

[@dilshadjumat4441]

the ans is a

[@ryandolm3958]

Rocky Papu what r u even solving for lmao there is no Unknown

[@gravysnake78]

If I hear log or logarithm again I'm going to crack

[@mohithrgowda8682]

give some more examples videos are quite short
