Which of these is correct? (1 point)

(8.8 * 10 ^ 8)(4.2 * 10 ^ 7) = 13 * 10 ^ 15

(2.9 * 10 ^ 5)(1.3 * 10 ^ 7) = 3.77 * 10 ^ 15

(4.6 * 10 ^ 5)(2.1 * 10 ^ 4) = 2.5 * 10

(9.9 * 10 ^ 7)(5.8 * 10 ^ 9) = 5.72 * 10 ^ 13

The correct equation is:

(9.9 * 10 ^ 7)(5.8 * 10 ^ 9) = 5.742 * 10 ^ 17

Therefore, none of the given options are correct.
