See your previous post.
1. To determine which number is greater than 4.3 x 10^9, we compare the exponents. In this case, the highest exponent is 9. Among the given options, the number with the highest exponent greater than 9 is option c, 5.3 x 10^9. Therefore, the answer is c.
2. Similar to the first question, we compare the exponents to determine which number is smaller than 6.5 x 10^-5. In this case, the lowest exponent is -5. Among the given options, the number with the lowest exponent smaller than -5 is option d, 4.6 x 10^-6. Therefore, the answer is d.
3. Comparing the populations, we need to compare the numbers without considering the exponents. The number of people in Nebraska is 1.8 x 10^6. Among the given options, Rhode Island has the smallest population, which is 1.1 x 10^6. Therefore, the answer is b.
4. To compare the given numbers, we need to compare them without considering the exponents. The options are 7.08 x 10^15, 7.65 x 10^14, and 7.65 x 10^4. Ignoring the exponents, the largest number is 7.08 among these options. Therefore, the answer is a.
