Answer:
Step-by-step explanation:
When you multiply base numbers together, you add their powers.
a^4 * a^ 7 = a^(4 + 7) = a^11 for example
So B is
18^(2 + 3 + 1) And it is the correct answer 18^6
Where did the 1 come from
5 is also 5^1. In integer always has a power of one if it is not stated that way.
