(4xexponet2)exponent 3

it amounts to 12exponent8......you power it to 3.

but in this equation it different..
(x exponentnegativ2 y exp.3) outside 2......... x ex. negative four y ex.6.............

im sorry it may seem wierd to read but i need help.

No. For your first problem:
$\displaystyle (4x^2)^3 = 4^3(x^2)^3 = 64x^{(2*3)}=64x^6$

You got the second one right:
$\displaystyle (x^{-2}y^3)^2=(x^{-2})^2(y^3)^2=(x^{(-2*2)})(y^{(3*2)})=x^{-4}y^6$

The general rules are:
$\displaystyle (ab)^n=a^nb^n$
$\displaystyle (a^n)^m=a^{n*m}=a^{nm}$

There are also conventions in fairly wide use on how to write mathematics
in plain ASCII. Some of which are:

1. Use brackets to make your meaning clear
2. Use * to denote multiplication
3. Use ^ to denote rinsing to a power so x^2 means x-squared
4. Use / for division, and use brackets to make it clear what is being divided by what.

I'm sure there are others that I have missed and may be supplied by others.
