    2log5(x) can be written as log5(x^2)

    then log5((x^2)/(3x))=1

    then x^2/3x=5^1

    x^2/3x=5

    And well, I forgot what you do next...

    I think he means 1= log5(5)

    Just out of interest, do you mean:

    2^(2x+3) = 3^(3x+2)

    or

    (2^2x)+3 = (3^3x)+2

    I mean the first one, and do these type of questions come up in a c2 exam generally?

    If it's the first one my photo was wrong. This one is right

    Also there's always one log question which is quite hard

    You are allowed to miss bases out for base 10 I think

    When you write something like log6,
    the base is automatically assumed to be 10.
