Define Logarithm: We are asked to find the value of the logarithm of 16 with base 4, which is written as log416. The logarithm of a number is the exponent to which the base must be raised to produce that number.
Identify Base and Number: We know that 4 squared (42) equals 16. This means that 4 needs to be raised to the power of 2 to get 16.
Calculate Exponent: Therefore, log416 is asking "to what power must 4 be raised to get 16?" Since we've established that 42=16, the answer to this question is 2.
Final Answer: So, log416=2. This is the final answer.
