Score: 0 of 1 pt 14 of 36 (13 comple 12.4.37 Use log b2 0.693 andor log b9 2 197 to find log b1 Select the correct choice below and, if necessary, fill in the answer box within your choice. o A. log b18 mype an integer or a decimal) O B. The expression cannot be found using the properties of logarithms.

Solution

Answer 12.3.37: 2.89 (As explained below)

log_b mn = log_b m + log_b n

So, log_b 18 = log_b ((2)(9)) = log_b 2 + log_b 9 = 0.693 + 2.197 = 2.89

Answer 12.3.39: - 0.154 (As explained below)

log_b m/n = log_b m - log_b n

So, log_b 6/7 = log_b 6 + log_b 7 = 1.792 - 1.946 = -0.154
