Answer 1

2 times 10^4 means 2 with 4 zeroes after it or 20000
4 times 10^6=4 with 6 zeros after it or 400000

compare

20000 and 4000000
we can see that 4000000 is 200 times of 20000
therefor the answer is C

we can also do
(4 times 10^6)/(2 times 10^4)=4/2 times (10^6)/(10^4)=2 times 10^2=200


answer is C

Answer 2

Your answer is C because when you solve for 2 x 10^4 you get 20,000 and when you solve for 2 x 10^6 you get 4,000,000 and 4,000,000 is 200 times more than 20,000.
