Everything is correct except question 4 question is A

1. To determine which value is greater than 4.3 x 10^9, we need to compare the coefficients (the numbers before the multiplication symbol) of each number. In this case, the coefficients are 2.1, 3.2, 5.3, and 7.4. By comparing these values, we can see that 5.3 is the largest coefficient among them. Therefore, the answer is:

c. 5.3 x 10^9

2. Similar to the previous question, we need to compare the coefficients to determine which value is less than 6.5 x 10^-5. The coefficients are 1.4, 2.5, 7.8, and 4.6. By comparing these values, we can see that 4.6 is the smallest coefficient among them. Therefore, the answer is:

d. 4.6 x 10^-6

3. To determine which state had a smaller population than Nebraska, we need to compare the coefficients. The population of Nebraska is given as 1.8 x 10^6 people. Let's compare it to the populations of the other states. The populations are 3.7 x 10^7, 1.1 x 10^6, 2.5 x 10^7, and 6 x 10^6. By comparing these values, we can see that 1.1 x 10^6 is the smallest coefficient among them. Therefore, the answer is:

b. Rhode Island: 1.1 x 10^6

4. To determine which value is greater among 7.08 x 10^15, 7.65 x 10^14, and 7.65 x 10^4, we need to compare the coefficients. The coefficients are 7.08, 7.65, and 7.65 respectively. By comparing these values, we can see that 7.08 is the largest coefficient among them. Therefore, the answer is:

a. 7.08 x 10^15
