sir I am from bangladesh. Many people of Bangladesh like your lecture. Thank you my teacher 🇧🇩🇧🇩🇧🇩🇧🇩

Thank you for posting. I've forgotten so much about logs and exponents from high school that it's great to be have a re-cap of these rules. It's a treat to go back and re-learn some maths fundamentals through your YT videos. Much appreciation from Australia.

i had a lot of trouble learning logs and their rules at first, but seeing this first would've made it much easier

[frederickwilt]

Thank you so much. Back in school having you are a teacher would have been a blessing.

[abirbiswas]

Sir please continue making these lecture series more frequently. It really helps a lot !!

[Orillians]

Thank you teacher so much. I am very glad that you finally started teaching in lessons :D.

[Kedatgahbelu]

I'm loving the long videos. Much respect 👊🏽😇

Posted this YouTube video to my Son's whats app to watch..

🔥Congratulations on your 100K plaque, well deserved. I once failed Algrebra I and subsequently earned an A in Algebra I because of the teacher. I became a teacher (32 years now) and always remembered the importance of how a teacher can make all the difference. With my best Regards. English teacher BTW not math 😂🔥

Exactly what I needed🥰
I was struggling with it in my maths class and now I know how to deal with it

[luisclementeortegasegovia]

Great lesson on logarithms! Thank you professor 👍

[marxstats]

Mr. H, could you kindly make a video about graphing trigonometric functions?

[dylanjayabahu]

I have a question about the domain that x>0. If the base is negative, doesn't that mean x can also be negative? For example, (-2)^3 = -8, so log base -2 of -8 should equal 3 no?

Thank you for the otherwise very clear and easy to understand video

[stephencindrich]

Must confess, if I ever knew this stuff, I don’t remember it.

[modularmoon]

Thanks for this video, very helpful! I just have on question, @5:30 you mention that 'any time you take a number to an exponent, the result cannot be negative or 0' but my calculator says -3³ == 0, is this statement assuming that some or all of these terms are positive, or just that the exponent is an even number ?

[RealModestTeacher]

One question, my Algebra II class just learned to find the domain of an exponential function, and we set the radicand greater than or equal to zero to do this. Why do you state that you cannot take the square root of zero and set the domain greater than zero instead of greater than or equal to zero? For instance, the domain of (x)^(1/2) should be, x >=o and can be graphed as such.

Good shit Professor H I need the refreshments of these logs.

[MA-rceo]

I appreciate you sir. Thank you for help students.

[PierTampa]

Thank you Professor, love your tutorials!!

Thank you for a nice introduction to logarithms. I have a question about the first property (around 3:08, when you use log5(1)=0 as example). You say that base doesn’t matter, but what if both base and argument are 1? Aren’t both log1(1)=0 AND log1(1)=1 correct expressions?
