Answer 5

ok scientific notation is just a fancy way of writing down large numbers used by guys and gals walking around in white lab coats and three pens in their pockets.

basically, what it means is, if you have a large number, you can express it as a power of 10.
for example. the number 400 can be expressed as 4 x 100. but 100 is 10 squared.
so 400 can be expressed as 4 x 10^2

Answer 6

similarly the number 1000 can be expressed as 1 x 1000 or 1 x 10^3
so how would you express 1 million in this notation?

Answer 7

1 x 10^6 ?

Answer 8

yup.
