Answer:
6.21 times more
Step-by-step explanation:
Assuming 2.04 x 10^11 was only a typo
you would need to first equal the powers of 10
so 20.4 x 10^10 and 3.28 x 10^10
now that they have the same powers

if it's asking for how many times i would approximate it to 6.21 times more
It is equal to 3000 to the nearest thousandth
Answer:
have you tries adding them together?
