Final answer:
The logarithm of 1 with base 4 is equal to 0.
Step-by-step explanation:
The expression log₄ (1) can be evaluated by determining the power to which the base, 4, must be raised to obtain the number 1. In other words, we are looking for the exponent that satisfies the equation 4^x = 1. Since any number raised to the power of 0 equals 1, the answer is: log₄ (1) = 0
