What's is (7x10^5) x (3x10^2)

Mathematics
1 answer:
denpristay [2]2 years ago

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
