Which describes the correct procedure when converting a number from scientific notation to standard notation if the power of 10 is -10? A). Move the decimal point to the left. B). Move the decimal point to the right C). Add 20 to the number D). Subtract 20 from the number.

The correct answer is - option A. Move the decimal point to the left.

Explanation:

Given:

10^-10

We know, powers in minus in scientific notation it will convert as inverse in standard notation:

10^-1 = 1/10 = 0.1

Similarly,

10^-10 = 1/ 100 = 0.01

So, by the given example we can see decimal moves to the left (0.1 to 0.01).

Thus, the correct answer is option A. Move the decimal point to the left.
