log_6 6^(1/3) = 1/3

Explanation:

Let's use laws of indices first.

Another way of writing " "root3 6" " is " "6^(1/3)" "

The definition of a log is:

The log of a number is the index to which the base must be raised to equal the number.
Apply this definition here: log_6 6^(1/3)

:.log_6 6^(1/3) = 1/3

Or, using index from: Log form and index form are interchangeable.

log_a b = c hArr a^c = b

If log_6 6^(1/3) = x, then 6^x = 6^(1/3)

x = 1/3
