Homework Help: Can someone give me a hint please for a log question

  1. Apr 18, 2007 #1
    1. The problem statement, all variables and given/known data

    Solve for Y in terms of X

    2. Relevant equations

    2log_5X/ log_53 - log_5Y = 2

    3. The attempt at a solution

    I know all the properties of logs, i just dont know how to apply them to this problem.

    The answers in the book are . y = 1/25x^2/log_53

    When i am studying, i can get through 99 percent of questions, but i always hit this 1 questions once every hour which i cannot answer and it just plays on my mind all day. :(

    Well for this part
    [tex]\frac{2\log_5 x}{\log_5 3}[/tex] Subtract that from both sides. Then Multiply everything by negative one and simplfy with the properties you already know.
