Answer:
To represent this operation as circles, we first graph what's in the parenthesis, which represents two circles with two circles each, that will give us the blur circle with 4 elements.
Then, each blue circle must be reproduced for times, because the expression 2x2 is multiplied by 4, giving as a result 16 circles in total. 4 groups containing 2 groups of 2 circles each.
The image is attached, it shows the graphic result.
