Question

I need help with this question

Answer 1

It is all determined by how many spaces and which way the decimal point moves.

Explanation:

So here are two examples

Example 1:

500000.00

To write this in scientific notation you would move the decimal place to the left.

You would move it 5 digits to the left so the exponent of 10 would be 5

`5 * 10^(5)`

Example 2

0.0000042

Here to write this in scientific notation you move the decimal place to the right.

You would move it 6 digits to the right so the exponent would be -6

`4.2 * 10^(-6)`
