Question 126801: 1. Use the logarithm properties to present the expression log(x + 10) - log x as the logarithm of a single quantity.
2.Fill in the blank to make a true statement. To solve 3 x = 26, we can take the logarithm of each side of the equation to get log (3 x ) = log (26). The power rule for logarithms would then provide a way of moving the variable x from its position as an __________ to the position of a coefficient.
3.Write the equation in logarithmic form (1/5)^-7=78125
4.Find the value of x: log3 9 = x

This is for an online game I am playing (ogame.com) that uses equations to determine the amount of resources you produce and also to determine how many resources you can have on one planet at one time. I have worked through a lot of the equation(s) already and this is what I am left with. I have asked a high school teacher for help and she was a bit stumped. Any help you could offer would be greatly appreciated. I believe this is the right category based on what I am told but if not could you let me know the correct place to submit it? Thanks

Question 129419: I need help with this question
A midwestern city finds its resident moving to the suburbs. Its population is declining according to the function defined by P(t)=poe-0.04t, where t is time in years and P0 is the population at time t=0. Assume that P0=1,000,000.
I need to find the population at time t=1.
b) how long will it take for the population to decline to 750,000?
c) how long will it take for the population to decline to half the initial number?
