Answer:
a. 2^4 or 16
b. 324
Explanation:
a. I think you can take 4 and put it as the exponent using properties of logs. so it becomes ln 2^4
b. you use the same property and get
ln 6^2 + ln 3^2 and use the addition/multiplication property one to combine them and get
ln 6^2 * 3^2
or ln 36 * 9
or ln 324
hopefully that works
