Answer 3

0.000000053

Answer 4

To determine how many times 4 x 10^4 is larger than 2 x 10^2, we divide the first number by the second number:

(4 x 10^4) / (2 x 10^2)

To divide these numbers, we divide the coefficients and subtract the exponents:

4 / 2 = 2
10^4 / 10^2 = 10^(4-2) = 10^2

So, 4 x 10^4 is 2 x 10^2 times larger than 2 x 10^2.

Therefore, the correct response is option 2: 2.

Answer 5

Apologies for the confusion. The correct response is indeed option 2: 2. 4 x 10^4 is 2 times larger than 2 x 10^2.
