Answer:
If you expand that, it comes out to 200000000, or in scientific notation, 2.0 × 10⁸.
Step-by-step explanation:
Starting with:
(7 × 10⁵) × (3 × 10²)
Since everything is multiplied, we can drop the brackets:
= 7 × 10⁵ × 3 × 10²
Now we can multiply seven by three, and both powers of ten:
= 20 × 10⁷
We can expand this now as
200000000
or in proper scientific notation:
2.0 × 10⁸
