I believe this is how it works. There's a rule involving multiplying exponents with the same base number, so:
8^(2x + y) is the same as
8^(2x) + 8^(y) which is the same as
8^x + 8^x + 8^y
= 15 + 15 + 25
= 55
If you would provide the correct answer, that would help with reverse engineering the rule/method, because I might be remembering the rule incorrectly.
