Help! Dont know how to do...

Ok, I got a huge fucking test tomarrow. If I fail the math portion I'm going to have to go to the worse fucking High school ever next year. EDHS in Michigan. I was getting tutored after school for math and when I'm about to learn something new thats on the test, she comes and picks me up. Now my only resort is the smart people here on Rune-Server.

I have more exponents. Heres a couple problems. Oh yea, teacher gave me an answer key, but thats not the point, I need to know how to do this for my test tomarrow.

Please explain how to do these, give the answer too!

(n^4)^-3 x 2n^4

2n^2y^4 x 4n^2y^4 x 3n
----------------------------------
3n^-3y^2

x
------------------------
(2n^0)^2

2m^-4
-----------
(2m^-4)^3

Please I really need help I'm really nervous about this test and must know how to do this!

Your equation format is incomprehensible.

Until you post it in a more legible form, you need to memorize:

(something^N)^M

= something ^ (N x M)

Why memorize? its logical? -.-

(A^n)^m = A^(n*m) cuz

(A^n)^m = (A^n)*(A^n)*(A^n) ... m times
A^n = A*A*A ... n times

So (A^n)^m
is

A*A*A*A...n times ...m times

A*A*A*A..n*m times
A^(n*n)

Owyeah I got an idea

Ill prove that (A^n)^m = A^(n*m)

Say m = 1

(A^n)^1 = A^n

Say m = 2

(A^n)^2 = (A^n)*(A^n) = A^(n*2)

Say m = 3

(A^n)^3 = (A^n)*(A^n)*(A^n) = A^(n*3)

Assume (A^n)^m = A^(n*m)

We will prove
that (A^n)^(m+1) = A^(n*(m+1))

(A^n)^(m+1) = (A^n)^m + A^n = A^(n*(m+1))
