Final answer:
To find logb (4/b), we can simplify the expression using the property of logarithms. Substituting the given values, we can solve for logb (4/b).
Step-by-step explanation:
To find logb (4/b), we can first simplify the expression. Using the property of logarithms that states logb a - logb b = logb (a/b), we have:
logb (4/b) = logb 4 - logb b
Given that logb 4 = 1.13, we can substitute the values and solve:
logb (4/b) = 1.13 - logb b
To find logb b, we know that the logarithm of a number to the base of that number is always equal to 1.
Therefore, logb b = 1. Substituting this value, we get:
logb (4/b) = 1.13 - 1
= 0.13
