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

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

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
