My teacher gave us some rules about numbers in the power of brackets.
Like 2^1/2
It was: a^1/n= n'root'a
(instead of a square root (2'root') or cube root (3'root') it was n'root'.)
Anyway, that equation is correct, at least with the brackets i tryed it with. But when we get numbers that isn't "1/n", but "n/m" he gives us this equation:
a^n/m = (a^1/m)^n = (m'root'a)^n
This equation I can't make correct. For example: I do 2^3/2 on my calc, and it gives me this: "4"
I put it in the equation:
2^3/2 = (2^1/2)^3
When I write this new setup on my calc it gives me this: "1"
I put it in the other equation and do it on my calc:
2^3/2 = (2'root'2)^3
It gives me this: "2.8284..."
There are four possibilities:
- I must be doing it wrong
- The equation is incorrect
- My calc is broke
- The laws of mathematics have changed
I am terribly sorry for my topic, I just found out that I forgot to put the bracket power into these: ( )
:uhh: :uhh: I just leave it standing so it won't be spam until one of the mods deletes it...
