Logarithmic scale | Logarithms | Algebra II | Khan Academy

Understanding how logarithmic scale is different from linear scale and why it could be useful

Missed the previous lesson?

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This man is a genius, when I did this at A level and university.. I didn’t understand it at all... and after only 5 minutes of viewing this video I understand Log, you sir are a genius!!

THANK YOU,

As a practicing Electrical Engineer a lot of the plots found in transistor datasheets and stuff often feature log linear, linear log, and log log plots for things like SOA and transistor curves. This video gave me some new insights for logarithmic scales I didn't know before (or more likely forgot)! thanks

[jeuxdeau]

WOW.... I've never visually understood Logarithms until now. I was only taught to solve them.

You are a life saver. I am in the middle of an Engineering degree and you are helping me get through it. I watch your videos all the time. Thank you!

This is a great video to recommend for students if they're struggling with logarithmic scales. It covers basically everything in 11 minutes.

[sunnysood]

Great video. I could never understand logarithmic scales until today.

[D.Wapher]

Ran into some problems about plotting with logarithmic scale, thanks for the great explanation on the basics. 🙏

[Sevnail]

Such a satisfactory and satisfying explanation!

[izdotcarter]

That’s an interesting speech characteristic

[iusyiftgklu]

Thanks man, this is the best explanation I've ever heard

[chisuun]

i think this would help my whole maths class understand logs better.

[JohanBrodd]

To all those who make tutorials with notepad on youtube, learn from this hero!

[andypampreen]

Great! I just wish the other type of log scale was also on Khan Academy. (Where the gridlines are NOT adjusted, as they really should have been in this video).

[dawatcherz]

this is the best explanation of a logarithmic scale i've ever seen

[hlomphomota]

Where was Khan Academy while I was in High School?

[dashduhad]

Do you have more videos about logarithms?

[realdeal]

great explanation buddy! thanks, it helped a lot.

I'm in pharmacy school and NOW is when i understand after this video

@kenufak 10^1/2 is just root 10...which is not futher reducible

10^x = 2, take the log of both sides

log 10^x = log 2

using log rule simplify the x down

x log10 = log2

x = log2 / log10
