Which describes the correct procedure when converting a number from scientific notation to standard notation if the power of 10

jenyasd209 [6]

Answer:

A. Move the decimal point to the left

Step-by-step explanation:

Given that:

The scientific notation = 10⁻¹⁰

Let recall;

That the standard notation usually took the form of an inverse:

For example;

Let say 10⁻¹ will be $\dfrac{1}{10}$ in scientific notation;

SO, $\dfrac{1}{10} = 0.1$

Now; we are given 10⁻¹⁰ as a scientific notation,

To standard notation, we get:

$10^{-10} = \dfrac{1}{100}$

= 0.01

Thus, it is true to say that the decimal point will be moved to the left side when converting a number from scientific notation to standard notation if the power of 10 is -10.
