Answer 1

The scientific notation of the planet Neptune is 2.793 x 10⁹

Scientific notation:

Scientific notation is the form of presenting very large numbers or very small numbers in a simpler form.

It can be written in the  form of multiplication of single-digit numbers and 10 raised to the power of the respective exponent.

The exponent is positive if the number is very large and it is negative if the number is very small.

The general form is

a × 10ᵇ ; 1 ≤ a < 10

Rules for scientific notation conversion:

• The base value must be 10
• The exponent must be a non-zero integer, that means it can be either positive or negative
• Coefficients can be positive or negative numbers including whole and decimal numbers

Given,

The planet Neptune is about 2,793,000,000 miles from the sun.

Now, we need to find the scientific notation of the given distance.

So, the scientific notation can be written as

=> 2.793 x 10⁹
