Remember the properties of logarithms. If you have ln81, you can pull out the power of two (9^2) and have 2ln9. Also, you could do ln9 + ln9 because 9*9=81 and ln9*9 = ln9 + ln9
With these properties, you can get 3lnx+2lny, which is 3u+2v according to the answer.
Hope I helped!

d. millimeters per hour.
we are given that,
carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.
since, according to the options, we see that,
water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.
we get that, the water can be measured by 'millimeters per hour'.
hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
