Question

How do I convert scientific notation to a real number?

Answer 1

A number in scientific notation is in the form

`a * 10^b`

To convert to a real number, write out `a` then move the decimal point depending on `b`'s sign.

If `b` is positive, move the decimal point to the right
If `b` is negative, move the decimal point to the left

For example,

`1.23 * 10^5`

Moving the decimal point 5 places to the right, we have

`123000`

---

`4.56 * 10^-5`

Moving the decimal point 5 places to the left, we have

`0.0000456`
