Explanation:

It is given that, the diameter of the sun is, d = 1.391 million kilometers

We need to represent the diameter in scientific numbers. A number can be written in scientific form as :

N=p.0* 10^q

Where

p is any real number

q is any integer

Since,
$1\ million=10^6$

and 1 km = 1000 m

The diameter of sun is:

$d=1.391* 10^6\ km$

$d=1.391* 10^9\ m$

So, the diameter of the sun is
$1.391* 10^9\ m$ . Hence, this is the required solution.
