Final answer:
The equivalent expression for log₃8 is 2*log₃3 or B) log₃3 log₃3.
Step-by-step explanation:
The property of logarithms that states log(x^r) = r*log(x) can be applied to find the equivalent expression for log₃8.
Given that log₃8 is the logarithm of 8 to the base 3, we can rewrite it as log(3^2) = 2*log₃3.
Therefore, the correct equivalent expression for log₃8 is 2*log₃3 or B) log₃3 log₃3.
