Question

What is the scientific notation of 0.01?

Answer 1

`1*10^-2`

You choose the `10`-power, so that the number in front of the power is between 1 and 10 (10 not included), or `1<=a<10`

Since `10^-2` represents `1//100` that was the right one to pick.

Extra:
If the question had been to put 0.01234 in scientific notation, you would still pick `10^-2` to get `1.234*10^-2`
