Question:

Express each as a sum, difference, or multiple of logarithms. See Example 2.

10 log5 √t


Data from Example 2

(a) Using Eq. (13.7), we may express log4 15 as a sum of logarithms:


(b) Using Eq. (13.8), we may express log4 (5/3) as the difference of logarithms:


(c) Using Eq. (13.9), we may express log4 (t2) as twice log t: 4

log4 (t2) = 2 log4 t

(d) Using Eq. (13.8) and then Eq. (13.7), we have
