d=1
Step-by-step explanation:

I'm going to reorder the left-hand side. Multiplication is commutative.

Since the bases are the same in
and the operation is multiplication, I'm going to add the exponents giving me:

So this implies we have two equations to solve:
and 
So the first equation can be solved by dividing both sides by 4 giving you
.
The second equation can be solved by subtracting 2 on both sides giving you
.
I believe you just have to draw 2 little lines in between AB and CD.
