    The equation does not correlate to this:

    Y = axb
    Where Y = cumulative average time per unit to produce x units
    a = the time taken for the first unit of output
    x = the cumulative number of units produced
    b = the index of learning (log LR/log2)
    LR = the learning rate as a decimal

    and the question asked to find LR

    The formula is not Y = axe, it is = ax^b

    When asked to find the learning rate you cannot be expected to use the formula (because with regard to b it would involves using antilogs and they are not in the syllabus).

    Finding the learning rate will only ever involve using the doubling rule and I explain this, with examples, in my free lectures on learning curves.
