Explanation:

log8 64 = a

cut log and base^a

64 = 8^a

8^a = 64

or a = 2

Answer:


8^a = 64, which gives
a=2.

Explanation:

When you see
\log_8(64)=a, think:
a is the number such that
8^a = 64. Mathematical intuition gives us that
a=2 immediately, but we can also work this out more methodologically:


8^a = 64\\(2^3)^a = 2^6\\2^(3a) = 2^6\\3a = 6\\a = 2

And this solution suffices.
