## Main Question or Discussion Point

My teacher gave us some rules about numbers in the power of brackets.

Like

It was:

(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 "

This equation I can't make correct. For example: I do

I put it in the equation:

When I write this new setup on my calc it gives me this: "

I put it in the other equation and do it on my calc:

It gives me this: "

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 wont be spam until one of the mods deletes it...

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: "
