Where
m is the real number
n is any integer
In this case, the average distance from the Sun to the Earth is given,
d = 150000000000 meters
There are 10 zeroes in this number. We need to write this number in scientific notation. It is given by :
So, the average distance from the Sun to the Earth is . Hence, this is the required solution.
