    subtract 1.45 from both sides:

    6.05 = 0.65 log(0.39E)

    divide both sides by 0.65:

    9.31 = log(0.39E)

    apply product rule of logs to the right side:

    9.31 = log(0.39) + log E

    calculate log(0.39) and subtract from both sides:

    9.72 = log E

    that looks like the form you are asking for, but if you want to solve for E, use the definition of logs:

    E = 10^(9.72)

    hope this helps!
