Answer:

2.391 × 10³⁰

Explanation:

3 × 10⁵ times means that we have to multiply the mass of the earth 3 × 10⁵ times:

7.97 × 10²⁴ × 3 × 10⁵ =

for the property of the multiplication we can "divide" the multiplication:

7.97 × 3 (we just multiply)

10²⁴ × 10⁵ (we apply the powers' properties)

23.91 × 10²⁹

Standard forms only accepts numbers from 1 to 9, so we have to correct this result by moving the point one place on the left:

2.391 × 10³⁰
