    This is for anyone here seeking extra math practice. So, not for me.

    I can do this easily. It's not for me. I posted test questions from the David Cohen textbook as practice for anyone seeking extra practice.

    A.

    1/125=5^-3

    -3=log(5,(1/125))

    B.

    e^0=1

    0=log(e,1) or 0=ln(1)

    C.

    5^x=6

    x=log(5,6)

    D.

    e^(3t)=8
    3t=ln(8)
    t=ln(2^3)/3
    t=(3ln(2))/3

    t=ln(2)

    write equation in log form

    A.
    9=3^2
    2=log(3,9)

    B.
    1000=10^3

    3=log(10,1000)

    C.
    7^3=343
    3=log(7,343)

    D.
    sqrt(2)=2^(1/2)
    1/2=log(2,sqrt(2))

    write an equation in exponential form

    A.
    log(2,32)=5
    2^5=32

    B.
    log(10,1)=0

    10^0=1

    C.

    log(e, sqrt(e))=12-> false, should be 1/2

    log(e, sqrt(e))=1/2

    log(e, e^(1/2))=12

    e^(1/2)=e^(1/2)

    Solving lots of different questions as you did helps visiting students. Your math work will help a high school or college student preparing for an upcoming exam. Remember: I am reviewing precalculus and precalculus only.

    If you do not see a section number listed at the very top of the page, I am not seeking help; it is just a general problem(s) to help visiting students. Moving forward, I indicate precisely why the thread was posted. For example, at the very top you will see PRACTICE MATH PROBLEMS FOR VISITING STUDENTS AND/OR MATH ENTHUSIASTS. You are a math tutor, former teacher and so I think of you as a math enthusiast. Feel free to answer any question you like or any thread you find interesting. Your math work shown also makes good study notes.
