not talking about this video but this is the most recent one


you are amazing you saved my grades

MR. Organic Chemistry Tutor, thank you for solving Logarithmic Equations and also checking the final solutions for extraneous roots.

U made me passing my Calculus exam after failed many times!

JG: a
Me: perfect! u did it again! thanks for helping me a lot, u rock

my first thought seeing the thumbnail

Hi, Im Presh Thalwalkar and welcome to ....

Ever since I started watching your videos, my grades are always the way I want them to be❤❤❤

Thought I'd try this on my own.
By the reverse power rule the equation becomes 2log x = (logx) times (logx). Dividing by (logx) i got (logx) =2. 10^2 =100.
X=100

Hi sir
Billion tks sir for solving my long outstanding question about these types of problems
I salute you sir

[Krazyrayglitter]

i really needed this last week, but thank you!

[Belladorphia]

I’m so confused with this math, it’s confusing, but I want to learn it, how are you coming up with these answers. Lol..

[ankitkumardubey]

Hi love your videos bro. You really help ed me literally everyday with organic chem. Please reply if your are seeing this

[kaco]

How do you convert a negative log to an exponential. Where does the negative go

[niranjanhalderb]

I have solved both the sums on my own I am very happy

Tomarrow my maths exam of polytechnic in Eletrical br.

[waynehuang]

Log x + log x= log x *log x
=Log x(1+1)=log x*log x
=>log x=2 or log x =0

Please, upload a video about " line jntegral "

[zissler]

So (log x)^2 = log(x^2) , couldn’t you just do
Log x times log x=>
log2x is that makes
Log 2x = 2logx which when you divide by log x =>
Log 2x - x = 2 which is only one of the answers what did I miss, seems like if I dropped the 2 from x^2 I need to account for it being positive or negative e but can’t figure it out.

[artiskey]

What's the difference between log x^2 and (logx)^2

[sanopann]

at 7:52 how can it be how did it become 1/4 why not 1

[seblewongelminlargh]

sure you are a life sever
