(a) log7 1/7 = -1
(b) log3 27 = 3
Step-by-step explanation:
(a) The logarithm of 1/7 to the base 7 is -1. This is because 7 raised to the power of -1 equals 1/7. Therefore, log7 1/7 = -1.
(b) The logarithm of 27 to the base 3 is 3. This is because 3 raised to the power of 3 equals 27. Therefore, log3 27 = 3.
