    Hi John,

    I just wanted to say a HUGE THANKYOU to you and for your free lectures and course notes. After sitting this exam 4 times, I was at my wits end, so decided to take a different approach to learning. Many people told me not to have the faith in open tuition as it is free, but here I am on results day with a huge smile on my face because I have passed.

    I can now move on to my professional level exams and will be one step closer to being qualified!!!


    Sam :D

    I am stuck on how to put it in the calculator.
    I first put in 3/4 x 5 x 2,000 squared, divided by 0.00014.
    On my scientific calculator this gives me 1.071428571 x 10 to the power of 11. How do I then go from here to putting in the cubed root and getting an answer of $4,750?
    Everytime I push the cubed root button it throws up an error.

    Please help :)
