Easy -1.8 This is a straightforward application of logarithm laws requiring only the identity log_a(x^n) = n·log_a(x) and recognizing that log_a(8) can be left as is, or using log_a(a^k) = k directly if rewritten as 8^a = (a^(log_a 8))^a. It's a single-step recall question with multiple choice options, making it significantly easier than average A-level questions.
