Question

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. Move the decimal point to the right. D. Subtract 20 from the number.

Answer 1

A. Move the decimal point to the left

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
`(1)/(10)` in scientific notation;

SO,
`(1)/(10) = 0.1`

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

To standard notation, we get:

`10^(-10) = (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.
