Question #c3c9a

Answer 1

Depends on what you are given.

Explanation:

If you are simply asked to give the scientific notation of a number, say 0.00000016, the decimal point ends up right after the FIRST whole number (except zero).

0.00000016 = `1.6` x `10^(-7)`
1,234,567,890 = `1.23` x `10^9`

The movement of decimal depends on what numbers you were given. A `color(blue)(positive)` exponent would mean that you have shifted the decimal from right to left.

1,000,000 = `1.0` x `10^6`
213,645.89 = `2.14` x `10^5`

A `color(red)("negative")` movement means that the decimal place moved from left to right.

0.004 = `4.0` x `10^(-2)`
0.00435 = `4.35` x `10^(-2)`
