1,989,000,000,000,000,000,000,000,000,000,000g.
b) The average radius of sun is about 695,000,000 meters.

Answer 1

these is the answer ..........

Answer 2

Given:

The mass of the sun is about $1,989,000,000,000,000,000,000,000,000,000,000g.$

The average radius of the sun is about $695,000,000 m$

To find:

To find the standard form of the given figures.

Step-by-step explanation:

• Here we need to find the standard form of the following figures.
• We can write this by raising the power and converting the number into decimal form.

Solution:

$1,989,000,000,000,000,000,000,000,000,000,000g\\\\=1.989 *10^{33}$

Similarly, we can do this for the average radius of the sun:

$695,000,000\\\\=6.95 *10^{8}$

Hence, the standard forms are following:

$1.989*10^{33}$ and $6.95*10^{8}$
