Gain a deep intuition for these exponent properties: (x^a)( x^b)=x^(a+b) and (xy)^a=(x^a)(y^a) and (x^a)^b=x^(a*b)

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 hate math but this guy made my life a little easier.
i agree
have a math quiz tommorrow with exponents, squares, and square roots and has this taught me more than my math teacher has
same
my parents used to force me to do khan academy every day during summer
nightmares are coming back
Your night mate came into my life ;(
same
Anyone using this khan academy during online corona school?
yep
I do 2 weeks of weekly scheduled content per day.
Yeppp
YES.
No
I just started college(I'm 30) and am having to take a basic math mini because I have forgotten everything lmao But I'm relearning everything through Khan Academy because the college material and teacher are a joke compared to this
Why because they books are $300 each 😭😭😂
Thank you sooooo much....A trillion times better than my maths teacher....You people are a great help😍❤😓
8th grade! I am just learning this now in algebra 1!
yup same Im a 9th grader doing this now
QueenOfRoblox yet you don’t know proper grammar? That’s sad
@@johndlcklk1489 Maybe english isn't their first language..
@@johndlcklk1489 who pays attention to grammar in a youtube comment section
N1y1211 N1y1211 I commented that a year ago! Anyways to fill you in she deleted the msg but in the msg she was gloating how smart she is.
OMG WISH Me LUCK I HAVE MID SEMESTER EXAM ITS START THIS WEEK
me 2
What did you get😂
@@therin7191 🥲💔
Oh My God.... Oh Allah! Help us in exam to success. Inshallah....
you’re heaven sent. you’ve saved my LIFE.
Isn't 11:22 wrong? When you are simplifying, you wrote 2*3, which is fine. But then you brought down x, as if it was x alone. Why didn't you bring down x^2 ??? According to the formula on top left, if xy^2, then it is also x^2 * y^2. So isn't 2xy^2 simplified into 2 * x^2 * y^2 ???
i’m crying over math homework.... wish me luck
Daniella MV rip
Thank you so much made so much more sense! thanks again
very helpful thank you love u sal
if you do even still make videos i would recommend having some sort of soft/lo fi beat in the background? i think it adds a lot of production quality and makes kids with learning dissabilities like add or adhd pay a little bit better attention..... just a thought
Interesting. Only thing that annoys me is the length of the vid. But it’s whatever :/
Good. Keep on going.
yes master
In the lesson "Using exponent rules to evaluate expressions" the solutions (via hints) isn't working.
I tried "= 3¹⁸ x 4⁻³⁰" (also without equal sign)
and I tried even the whole steps shown via hints "((3³)(4⁻⁵))⁶ = (3⁽³⁾⁽⁶⁾)(4⁽⁻⁵⁾⁽⁶⁾) = 3¹⁸ x 4⁻³⁰"
So what's wrong with my solutions? Why doesn't it work? I am really stuck here.
thanks shabaz
get this man some water
What if the base is different like 5(2)•4(2)
Solve it by hand 25*16
My teachers video is double the length a lot more slow and a lot more boring, thank you.
the kum
When you dont pay attention in class and the teacher says we got a test first thing in the morning
end my suffering
LMAO
I think this video is going to be helpful!!!!
thanks
I’m looking back at this for 9th grade😁✝️
Nice😀
I understand but what if I have something like 3 to the -1th power?
KrydiCraft,it will 3.
I mean,it will be 3.
3^-1=.333
QueenOfRoblox shut up and stop bragging people are actually trying to learn the original commenter asked a QUESTION so unless u have to offer some advice or the answer u need to stop shaming people
Yupp it will be 3
@ 10.34 what happened to the 1? where did it go?
this makes so much sense
At 10:28 shouldn't you write the ''1'' down below. So that the final answer becomes 7 instead of 6x^7 y^6?
WHAT AM I DOING HERE.
yamoteee SAME
SAME HERE BUD
can u tell us the properties
This 10 years ago ???
I just started 8th grade honors
What software do you use?

how is this 8th grade math. im in the grade level 6th grade math class and this seems easy. imagine the advanced classes
Trust me it's not
Aubrey T it’s not but you probably know that now
Ur in 10th grade now was it easy
what is the 0 power of 0
