Determine the values of mm and nn when the following average distance from the Sun to the Earth is written in scientific notation: 150,000,000,000 mm.

m × 10^n = 1.5 × 10^11 mm

m = 1.5

n = 11

Explanation:

Scientific notation is written in the form;

m × 10^n

Where m = a number between 1 and 10

And n is the power or exponent.

To convert

150,000,000,000 mm

we need to know the number of movement of the decimal before we reach a number between 1 and 10.

There are 11 movement to reach 1.5 and since the movement is to the left then the power carries a positive sign. So, the scientific notation is given as;

m × 10^n = 1.5 × 10^11 mm

m = 1.5

n = 11

the correct choice is a .
