Which of the following is greater than 4.3 × 10^9

A. 2.1 × 109
B. 3.2 ×109
C. 5.3 × 109
D. 7.4 ×108
I think it's either C or D, but I can only choose one.

A. 2.1 × 10^9

B. 3.2 ×10^9
C. 5.3 × 10^9
D. 7.4 ×10^8

well, D is 0.74 x 10^9

so I guess C, eh?

D is 7.4 x 10^8

The ratio of the correct number to 4.3*10^9 is greater than 1:

n/4.3*10^9 > 1. So the answer is C.

which of the following is greater than 4.3 x 10^9

To determine which of the options is greater than 4.3 × 10^9, we need to compare the given values.

Let's convert the options into standard decimal notation for easier comparison:

Option A: 2.1 × 10^9 = 2,100,000,000
Option B: 3.2 × 10^9 = 3,200,000,000
Option C: 5.3 × 10^9 = 5,300,000,000
Option D: 7.4 × 10^8 = 740,000,000

Now, comparing these values to 4.3 × 10^9, we can see that:

4.3 × 10^9 < 5.3 × 10^9 (Option C)
4.3 × 10^9 > 7.4 × 10^8 (Option D)

So, based on our comparison, the correct answer is option C: 5.3 × 10^9.
