Final answer:
The expression -log3 1 can be evaluated by applying the definition of logarithm. In logarithms, the base is raised to the power of the logarithm to get the original number. In this case, the base is 3 and the logarithm is -1. Therefore, the expression becomes 3^(-1) which is equal to 1/3.
