So, as you may or may not know, I'm taking my 'O' levels here as
a private candidate, and I'm right now doing this excercise in the
textbook I have here. I stumbled upon this question that goes like
this:
Express 74 cubic CM in cubic M, giving your answer:
(a) as a decimal;
(b) in standard form.
The answers given were 0.000074 for (a) and 7.4
x 10^-5 for (b).
Now, I am checking these answers with my calculator, and for
some reason, it is showing 7.4 x 10^-5 as 0.00074.
I'm not sure who's wrong here, though I'm suspecting my calculator,
as impossible as it might sound, might be trying to be funky here.
Can someone please help and clarify? Also, can someone clear up on
how the exponential notation works?
