these types of questions look really hard but at very simple (usually :-) ).

The thing to spot is that the 2 base numbers, here 9 and 27 are both powers of 3. We will convert the numbers to 3 and then we will have "3 to the power of whatever" equals "3 to the power of something else". So, the 2 powers must be the same thing.

So now we can say that

CHECK:

so we are correct.
