1.

w%5E%28-5%29+=+1%2F%28w%5E5%29 since x%5E%28-k%29+=+1%2F%28x%5Ek%29 where k is some positive number.

=======================================================

2.

%28d%5E%28-3%29%29%5E%28-4%29+=+d%5E%28-3%2A%28-4%29%29+=+d%5E%2812%29 Note: you multiply exponents in this case.

So %28d%5E%28-3%29%29%5E%28-4%29+=+d%5E%2812%29
