    1) factor out 5^2k
    5^(2k)(5^2-1)
    2) simplify
    5^(2k)(24)
    so

    No! It took me a few minutes to think about what I needed to do. I am in school right now and my major is secondary mathematics education, so it is important for me to actually know this!Don't lose confidence! If you cant figure out a problem the first time, leave it and come back later!
