Correct choices: the first and second expressions.

Work:
- (36^{5/16})(6^{-1/2}) = (6^2)^{5/16}·6^{-1/2} = 6^{10/16}·6^{-4/8} = 6^{5/8}·6^{-4/8} = 6^{1/8}.
- (6^{5/8})(6^{-1/2}) = 6^{5/8 - 4/8} = 6^{1/8}.

The others are not equal:
- 6·6^{7/8} = 6^{15/8}.
- ^8√(6^5) = (6^5)^{1/8} = 6^{5/8} (appears twice).
