1. e^ln3 - 2lnx


2. 2(lnx)^2 + lnx - 1 =0

3. d/dx (e^x . e^e^x)

  • calculus -

    1.
    e^ln 3 = 3
    so
    3 - ln x^2

    2.
    2z^2 +z-1 = 0
    (2z-1)(z+1) = 0

    z = 1/2 or -1
    ln x = 1/2
    e^ln x = x = e^.5 = 1.65
    ln x = -1
    e^-1 = 1/e = .367

    3.
    do not understand notation
