Quite simple for you Math Genius but I'm struggling to understand the following equation. (I've only just started an introductory course in Mathematics and I'm keen to learn) :)
I'm getting 2 answers
On my scientific Calculator $= 5.4$
On this website $= -5985$
My formula below. First I would like to know which one is correct or an explanation as to why they can both be correct. if someone could then break it down for me so I can understand where I have gone wrong.
