    can anyone please help me with these?
    i've got a final due on Tues, Dec 9th and this test is kickin' my butt.

    Solve:
    log_2(6x+3)=5




    log_x (x+6)=2


    Express as single log:
    log_3(x-3)(log_3y+2log_3 z)



    Solve:
    log x + log(x-15)=2



    32^3x = 8^x+3




    2^2x-3*2^x-40=0
