Step-by-Step Solution

To solve the problem log68 \log_6 8 , we need to express the number 8 as a power of a base that simplifies the logarithm. We can write 8 as 23 2^3 , because 8 equals 2 multiplied by itself three times.

Let's use the power property of logarithms, which is:

  • logb(an)=nlogba\log_b (a^n) = n \log_b a

Applying this property to log68\log_6 8, we have:

log68=log6(23)\log_6 8 = \log_6 (2^3)

Using the power property, this becomes:

log6(23)=3log62\log_6 (2^3) = 3 \log_6 2

Therefore, the expression for log68\log_6 8 in terms of log62\log_6 2 is:

3log623 \log_6 2.

Answer

3log62 3\log_62
