appeal, please answer it serious? 1. Express as a single logarithm. Assume that x and y represent positive numbers.
5 log base 3 x + 6 log base 3 y^(2/3) - 2 log base 3 square root x^3 - 3 log base 3 y
2. A bacterial culture starts with 300 bacteria. After 3 hours the estimated count is 48000. What is the doubling period?
3. After 5 weeks, the mass of a sponge has decreased from 1kg to 8kg. Using proper form, find the half-life in hours, to one decimal place, after finding the exact value.
4. Helmut spent the days driving a farm tractor. The noise level was 98db. Squid word worked on the sound crew for the rock band " Devil's Crustaceans". The noise level was 120db. How many times more intense was the noise level at the rock concert than on the farm tractor?
