(5x^4)^2 z^2/5z^4 = ?
(5x^4)^2 = 25x^8. After that there are a multitude of ways of reading the expression, some of which can be simplified, some not.

(5x^4)^2 z^2/5z^4 = 5^2 x^8 z^2 / (5z^4)
= 5 X^8 / z^2

expand remember exponent laws
(aB^c)(dB^e)=(a)(d)^(c+e)
(5)(5)^(4+4) when (5x^4)^2 is expanded
=25x^8z^2/5z^4 take out common facotr out on top and bottom
=z^2(25x^8)/z^2(5z^2) it's important to remember exponent laws when facotring out exponents z^2(z^2)=z^4 still
z^2 cancel out leaving final solution
=25x^8/5z^2 or (5x^4)^2/5z^2

((5x^4))^2 (z^2)
------------------- is that the expression?
(5z^4)
It then becomes (5x^8)(z^2) ((625)*(625))*(x^8)*(z^2)
-------------- = ------------------------------
625z^4 ((625))*(z^2)^2
((z^2)^2)this is another way to write z^4)
The z^2 and 625 cancel, and so, you are left with:
625x^8
--------- THAT IS THE FINAL ANSWER
z^2
