Answer 1

1,391 10^3

I hope you mean Scientific Notation. This would be the answer for it. Hopes this helps.

Answer 2

Step-by-step 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 :

$N=p.0\times 10^q$

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:

$d=1.391\times 10^6\ km$

$d=1.391\times 10^9\ m$

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