Answer 1

2.149 * 10^3

Explanation:

The standard form of writing a scientific notation is expressed as;

A * 10*n

A is any integer between 1 and 10

n is any integer

Given the diameter of the moon = 2.149miles

Expressing in scientific notation;

2,149 = 2.149 * 10^3

Note that we shifted the decimal point 3 times to the back That's why the power is positive 3
