Question

How do you write `4.00005times10^7` in standard notation?

Answer 1

`40,000,500`

Explanation:

1. This is the reverse process of writing standard scientific notation;
2. First, look at the exponent which is 7;
3. Move the decimal point 7 times to the left bearing in mind that moving the decimal to the left means a negative exponent, and that would cancel out the exponent;
4. Position your decimal and apply appropriate commas to identify its place value and readability;
5. The standard notation is `40,000,500`.
