this may be the best video ever created. When I say you saved my grade, you saved my life.

Omg!! Thank you so much!!! I CAN'T THANK YOU ENOUGH! OMGGG. I have a test soon and I am so confused. You are my saviour oh my goshhh!!! THANK YOI SO

Absolute ingenious explanations here Mario. Perfect timing for my Pre Calc Final tomorrow, this has saved me so many questions. I truly appreciate the elaboration throughout the lesson.

[Vibe-core]

man i can't explain enough how much your videos help me, only person on youtube that explains this way. I cant explain how you do it but the way you use your vocabulary and hand movement makes your information deliver like butter. You single handedly cleared 2 whole 12th year IB chapters of mine in less than 50 minutes and I cant wait to ace this test and brag on my classmates because I found the source of gold on youtube.

This video is amazing. When my mom tried to explain logarithms to me, i could not understand a single thing. But when you explained it, i understood clearly, and was immediately able to do the questions.

[Seb-yx]

I like learning logarithmic equations!

[jeriesakroush]

I LOVE YOU MAN. WHAT AN INSPIRATION SERIOUSLY

[hangwannabe]

As someone who has always been fuzzy on logarithms, this really helped me out. Thanks.

[mohammedhafiz]

I have recently found your videos.
Excellent, Great, so cool, learnt in five minutes what took weeks in my school days.
Keep up the good work.please keep on the small details that's what makes the difference.
Thanks

[harrisonbrunson]

learned more in this 1 hour video than I have from my college algebra teacher in the past 6 weeks

[HarshitSharma-tyyu]

Best log videos ever created. THANKS MAN👍👍👍

[sereniarabbit]

you've saved me for finals week god bless your soul :>

[Skzlover-mr]

Thank you Mario! This video helped me get ready for my CPC. My teacher takes a bit time to explain in my alg 2 class!

[xxfaithx]

Thank You So Much, best log video out there

[RaspberryStrudel]

Thank you so much! This is the perfect video, amazingly explained. Helped me so much when last-minute cramming for a test.

[AliEsla]

Thank you so much! That is crystal clear!

[acatalepsia]

sat thru the whole thing and u explained everything i needed :D i was so happy towards the end when i was able to solve the problems myself >///< thank u again mario !

[Budgeman]

Basically, when solving for logarithms p, it’s best to keep things as simple as possible?

[norahalhunayshil]

In the Questions 46)
How about x = 2 and 6

Hello! I really appreciate this video; I learned a lot from it. However, I have a question about graphing logarithms. I’m unsure if you covered transformed graphs involving vertical and horizontal compressions. I believe it would be a helpful addition to your method. Please let me know. Thank you!
