Answer:
C: 2^32
Explanation:
The problem asks us to find the correct expression that is equivalent to the expression "2^30 + 2^30 + 2^30 + 2^30" , so we need to simplify it and see what expression will result from it:
2^30 + 2^30 + 2^30 + 2^30
= 4 * (2^30)
= (2^2) * (2^30)
= 2^(30+2)
= 2^32
So the right answer is letter C: 2^32
