Question

Which expression is equivalent to 5^{10} · 5^{5}

A. 5^{2}
B. 5^{5}
C. 5^{15}
D. 5^{50}

Answer 1

C should be correct

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.
