Final answer:
To express log 4(18.11) as a sum of logarithms, we can rewrite it as log 4((4 * 4.53)) and apply the property of logarithms.
Step-by-step explanation:
When expressing log 4(18.11) as a sum of logarithms, we can use the property loga(b * c) = loga(b) + loga(c).
Since 4 is the base, we can rewrite the expression as log4(18.11).
Breaking down 18.11 into factors, we can rewrite it as log4((4 * 4.53)).
Applying the property, we can express it as a sum of logarithms: log4(4) + log4(4.53).
