8th grade on Khan Academy: 8th grade is all about tackling the meat of algebra and getting exposure to some of the foundational concepts in geometry. If you get this stuff (and you should because you're incredibly persistent), the rest of your life will be easy. Okay, maybe not your whole life, but at least your mathematical life. Seriously, if you really get the equations and functions stuff we cover here, most of high school will feel intuitive, even relaxing. (Content was selected for this grade level based on a typical curriculum in the United States.)
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.
For free. For everyone. Forever. #YouCanLearnAnything

I doubt Sal (or anyone else from Khan Academy) will ever see this, but if you do, know that this helped me immensely! I'm so happy to be able to understand it for my test tomorrow. Everything in these videos are always done in such an easy to understand manner and it's very much appreciated (also, I very much appreciate the color coding!)

XxTHATGUYxX122 If the bases are different, they cannot be combined using exponent rules. You would have to evaluate each one separately before multiplying or dividing those answers. Don't mix apples and oranges. :)

thanks

[@TurboCraftBros]

Dude that helps so much with my math homework! Thanks, ur awesome!

[@jacenouzen]

I thought in math... having train math is wrong,. 1 + 2 = 3 = so on and so on,,, something like that.

[@James-yv1qq]

I have test in this coming up, and you just saved my life! it makes way more sense! THANKYOU!

[@jenbroccoli861]

I love the colors in the video, lol!!!!! 😍😍😍😍😍😍❤❤❤❤❤❤❤✨✨✨✨✨✨✨

[@holasoyalejandro]

It helped me a lot thanks

[@xentaza]

wat if it had a different base

[@missamericana6336]

If it has a different base, it stays as it is. I know I’m 6 years late😂

[@Nil_the_Doorless]

@@missamericana6336 if one base is a multiple of another it can be simplified 2^3 * 4^6 = 2^3 * 2^12 = 2^15. divide the base by 2 and multiply the exponent times 2

[@supatchube]

Haha quarantine

[@dominikkannenwischer9923]

Super helpful video! Thanks Khan Academy!

[@winisning]

You are a life saver, I have an algebra test tomorrow and I’m freaking out I hope I pass

[@melaniejones4608]

Did you pass lol

Thank you Khan academy

Thank you so much!

explains so much

[@pandagiantgiantpanda3317]

thanks man

[@newtnewt1561]

But what if it's a decimal

[@georgied4073]

At the very end of the video you had the 5/4 1/x and then y. How come it became y/1 and not 1/y sorry probably really dumb question.

[@londonreighn7123]

thank you ig
