#### Solution Preview

PART ONE:

(3n^5 w)^2 /(n^3 w)^0 == ??

Note: I have used * to denote multiplication and make the notations clearer.

Anything raised to the power of 0 is ALWAYS equal to 1. Therefore the denominator which is ((n^3)*w)^0 = 1. And any entity divided by 1 remains unchanged. So we are left with only the numerator which is

(3*(n^5)*w)^2.

In order to evaluate a 'product' raised to a power, we must raise each of the 'members' of the 'product' to the same power. So in our case the 'product' is (3*(n^5)*w). So you raise each member to the same power, which is 2.

Thus, (3*(n^5)*w)^2 = ...
