    solve for x

    1/ (ln x)^2 = 3

    2/ lnx = log2

    3/ ln2 . ln4x =3

    4/ ln (x-2) = (lg 3)^2

    5/ ln 4x = log3 . log5

    6/ log(x-1) = ln(e^2-1)

    This looks like homework and in fact a rather easy one. Go and read carefully once again the definition of logarithms in your notes/book and then check its basic properties and THEN try the above, and if afterall this you still get stuck somewhere write back.
