Using the properties
n\log_a(b) = \log_a(b^n) and
\log_a(b) + \log_a(c) = \log_a(bc), we have

2 log₅ (5x³) + 1/3 log₅ (x² + 6)

= log₅ (5x³)² + log₅ ∛(x² + 6)

= log₅ (25x⁶) + log₅ ∛(x² + 6)

= log₅ (25x⁶ ∛(x² + 6))

Trying to parse the choices you listed is ... difficult. I trust you'll be able to figure out which one matches best on your end.
