Answer:
C should be correct
Step-by-step explanation:
I am not sure if you or anybody else does this another way or maybe the same way, who knows.
Anyways, what I did here was just simply add the powers, and no, not the base, I mean what it is being multiplied by.
When I did this, I got 5^15, but I had to check to make sure, which is what I did
5^10x5^5 is 30517578125
And guess what.
5^15 = 30517578125
So the answer is C, and I hope my explanation helps in a way.
