Did your class and/or textbook not cover log rules...? :shock:growold61 said:
The rules are as follows:
. . . . .log<sub>b</sub>(m) + log<sub>b</sub>(n) = log<sub>b</sub>(mn)
. . . . .log<sub>b</sub>(m) - log<sub>b</sub>(n) = log<sub>b</sub>(m/n)
. . . . .log<sub>b</sub>(m<sup>n</sup>) = n log<sub>b</sub>(m)
For lessons with worked examples of how to use log rules, try any of the online lessons listed here:
. . . . .Google results for "log rules"
Once you have reviewed the above rules, and perhaps have studied a few online lessons, please attempt the exercise. If you get stuck, or are unsure of your solution, please reply, showing all of your work and reasoning.
Thank you!
