Thanks for answering the answer is correct:)
but how do I answer this quesiton with logs appearing in at least one of the steps?

There have been a bunch of problems like this one recently. You might want to check the 'recently solved' before posting a problem that is already solved several times.
In tis problem, you can elininate the Log2 from both sides. You can just 'know that since a Log2 on the left is equal to the Log2 on the right, then the values are the same. Thus .
If you want to go a different way, take both sides of the equation and use the values there as exponents on the power of 2. So 2^(log2 1056) = 2^(2^a+5 + 2^a).
That becomes 1056 Log2 2 = (2^(a+5) + 2^a) Log2 2. Since Log2 2 = 1, you get to the same equation as above.
a = 5
