    Where to start?
    I am having a problem starting this question. I have tried 3 ways and every time I am getting the wrong answer.

    The problem is:

    Solve for X:

    10^2x-1=10^10

    For anyone who can help me start this I would really appreciate it. You are the best!

    Please use proper grouping symbols.

    Is it

    or



    I will assume the former:



    What is log(10)? That makes it easy.

    I am assuming I would take it from there in by doing:

    (2x-1) log(10)=10log(10)

    2x-1 = 10

    2x = 11

    11/2

    and that's what x = or 5 1/2
