    my computer is messing up and I can't use any of the equations.. nPk is supposed to be expressed similar to a logarithm where n and k are numbers expressed lower than P. Same for 8P3. I forget what the values are called though. If this makes any sence.. So would it still be a?

    Thank you. What is it called when a number is expressed lower like that?
