Hello :)
I think they ask you to use the numbers below to solve the theoric equation, and the answer is suppose to be 5.
The power of a number is the result of the exponentiation.
Let's do an example.
We are searching for :
$$2^{x}=5$$
And, we use theoric formula.
$$M = a^{\log_{a}{M}}$$
$$5 = 2^{\log_{a}{5}}$$
Now, you have to isolate a, and you have your answer.
Hope it helps! :) See you soon :D
