The answer should be B or ( 7 + 6) log six ( y + x)

Hope this helps!
We have the following expression:
 7logb (y) + 6logb (x)
 By properties of logarithm we can rewrite:
 logb (y ^ 7) + logb (x ^ 6)
 Applying logarithm properties again:
 logb ((y ^ 7) * (x ^ 6))
 Answer: 
 logb ((y ^ 7) * (x ^ 6))
