Points: 0 of 1 Use the properties of logarithms to evaluate the expression without the use of a calculator. \[ \log _{7} 1 \]

Step 1 ：Use the properties of logarithms to evaluate the expression without the use of a calculator: \( \log _{7} 1 \)

Step 2 ：By the definition of logarithm, any number raised to the power of 0 equals 1. Therefore, \( \log _{7} 1 = 0 \)

Step 3 ：Final Answer: \( \boxed{0} \)
