A: 9x 10^-28

B: 2x 10^-24
how much larger is B than A

To find out how much larger B is than A, we can divide the value of B by A:

B/A = (2 x 10^-24) / (9 x 10^-28)
B/A = (2/9) x 10^-24 / 10^-28
B/A = (2/9) x 10^(-24 - (-28))
B/A = (2/9) x 10^(-24 + 28)
B/A = (2/9) x 10^4
B/A = 2/9 x 10000
B/A = 20000 / 9
B/A ≈ 2222.22

Therefore, B is approximately 2222.22 times larger than A.
