Answer:
A
Explanation:
I'm assuming p is an exponent.
You can multiply the exponent p with 9
8^9p = 8^18
Now we know that some number times the exponent 9 gives us 18.
Now, we isolate for p, by putting 9 on the other side, we know we can do this because both number have the same base (8)
therefore, 9p=18
p=18/9
p=2
