    Which book do you use?

    Doesn't the book has a solution bank?

    I won't be able to answer all your questions, i am preparing for physics. You may have to seek help from someone else.

    Its best you post the questions you don't understand on the forum.

    Download the new book and use it. It has a solution bank, it is very difficult to study without the solutions.

    Mate, the first question the OP asked has got me stumped.

    So the RHS, would it be logbase3 (3)^2 (6x^2-19x+2)?

    so its logbase3(3-2x)=logbase3 (3)2 (6x^2-19x+2)

    and then raise the LHS by power 3 and then RHS by power 3, to get

    2-3x=9(6x^2-19x+2)???

    I consider logs the easiest chapter.

    This is the only topic on which i don't make mistake while attempting AEA questions.

     log_3(2-3x) = log_9(6x^2-19x+2) \implies log_3(2-3x) = \dfrac{log_3(6x^2-19x+2)}{log_39}

    Remember,  log_39 = log_33^2 = 2log_33 = 2

    Now try to do it.

    Nah ... logs are fun



    Noah parked his ark after the storm and sent the pairs out "Go forth and Multiply" he said

    After a while he sent his sons out to check progress

    There were babies everywhere; antelopes to zebras

    But no baby snakes



    They asked the snakes what the issue was and the snakes said "can you cut down some trees for us"

    Ok ... job done

    A while later they check again ... loads and loads of baby snakes

    "How did the trees help" asked Noah



    "Well", said the snakes, "we are adders, so we needed logs to multiply"

    okay can you tell me how you would approach the first question the OP posted. I also don't know if what I am doing is right now... I posted my method above. Will give rep.
