So last time, some months ago when i asked for help with a problem, a lot of you fine people helped me out! Now I need some more help. So here goes:
Just the first picture...

ugh, maths...
i'm sure someone with smarts will help though

Yes I dont like math either, but I have to take this course. Wish I did it 8 years ago though
Hmm, alright. So far no one can help... in the mean time Ill do some exponential growth. Not that its any easier... but anyway!
OK, not THAT hard... I hope.
First of all you gotta remember:
Therefor:
From now on it's simple mathematics:
4^3 and 4^-3 cancel each other out.
Now since you add up the exponent on multiplication, you obviously subtract it on division.
Therefor:
because
q.e.d.
Hope you understand.
Edit: Typo
First of all you gotta remember:
Code:
12 = 3 x 4
Code:
12^3 = (3x4)^3 = 3^3 x 4^3
Code:
(3^3 x 4^3 x 4^-3)/3^-1
Now since you add up the exponent on multiplication, you obviously subtract it on division.
Therefor:
Code:
3^3 / 3^-1 = 3^4
Code:
3 - (-1)= 4
Hope you understand.

Scratches head
To Maef! AAAAaaaaaaaaaaaaaaahhh, thanks man!! It was that simple? I understood. THank you very much!! Karma coming your way
Yes i understood anyway, even though you made a typo. Since its like you wrote now: 3^3/3^-1 its 3^3- (^ -1) Got ya!!

So when did you have this kind of math in school? How old are you Maef?
You could also just multiply them out.
3^-1 = .3333 (repeating) or 1/3
and so on.
Then when you get an answer you just convert back into exponential form.
3^-1 = .3333 (repeating) or 1/3
and so on.
Then when you get an answer you just convert back into exponential form.
I can help you.....split 12^3 up in 4*3*4*3*4*3 ...then spilt 4^-3 up in (1/4)*(1/4)*(1/4)..... 3^-1 is the same as muliplying the top with 3 .....4 and (1/4) equals 1 so you are left with 3*3*3*3 that is the same as 3^4.
Hope you understand......

Yes thanks, but I have to write the nrs always as an exponent. On this one. Others i probably could write it like you suggested. But have to follow what the teacher saidMorbiD.ShoT wrote:

Ugh... not too long ago. A couple years.
I graduated last summer being 21 now (The school system is quite different here in Austria than it is in the US)

Well looks like I'm too late but just a small short and easy tip, when you have negative exponents over another number, bring it "down", there fore chaning it to a posotive one
Ah, I see. Im from Norway my self. Took high school from I was 16-19. Could have taken this kind of math in second grade... but I didnt know that I would want to be a dentist hehe. Its too bad. Im 25 now. So im struggeling with it. Dont even remember the simplest things. I meant didnt. Its coming back to me now though. Thanks everyone for your help!maef wrote:

The rule in maths is this
Indices once multiplied together add each other up.
Eg
3^7 x 3^7 = 9^14
Capiche?
Same goes with division, they minus each other.
So for the.... meh I got confused.....

Err... I believe 3^7 x 3^7 is actually 3^14zimmer92 wrote:

lol yeah 3^7 times 3^7 aint 9^14 but 3^14....but then again i think he may be joking about that part
SteikeTa, are you just doing this for the answers? Cheater...
Lol just kidding.
Lol just kidding.
Hehe... no I already know the answer, but I needed to know the "procedure" to finding the answerryan_14 wrote:

Meh, yeah, I put in 3^14 first and then i changed it. Because I got confused funnily enough.voodoodolphins wrote:

This is happening to me a lot lately.....I wonder why.....
