Use common logarithms or natural logarithms and a calculator to evaluate the expression. \[ \log _{18} 16 \] Use the change-of-base property to rewrite the given expression in terms of natural logarithms or common logarithms. $\log _{18} 16=$ (Do not evaluate.)

Step 1 ：Given the expression \(\log _{18} 16\)

Step 2 ：We can use the change-of-base property to rewrite the given expression in terms of natural logarithms or common logarithms. The change-of-base formula is \(\log_b a = \frac{\log_k a}{\log_k b}\), where k can be any positive number except 1.

Step 3 ：Using this formula, we can rewrite the expression \(\log _{18} 16\) as follows:

Step 4 ：Using natural logarithms (base e): \(\log _{18} 16 = \frac{\ln 16}{\ln 18}\)

Step 5 ：Using common logarithms (base 10): \(\log _{18} 16 = \frac{\log 16}{\log 18}\)

Step 6 ：\(\boxed{\log _{18} 16 = \frac{\ln 16}{\ln 18}}\) or \(\boxed{\log _{18} 16 = \frac{\log 16}{\log 18}}\)
