Final answer:
To evaluate logb(5/3), use the property logb(a/b) = logb(a) - logb(b).
Step-by-step explanation:
To evaluate logb(5/3), we can use the property of logarithms that states logb(a/b) = logb(a) - logb(b). Substituting the given values, we have:
logb(5/3) = logb(5) - logb(3)
= 1.609 - 1.099
= 0.510
Therefore, logb(5/3) = 0.510.
