What is the product of 3.4 * 10-14 and 1.8 * 1028?

6.12 * 1014

9.4 * 1014

5.2 * 1042

6.12 * 1042

Remember

(x^m) (x^n) = x^ (m+n)

and commutaitve property

(3.4 times 10^-14) times (1.8 times 10^28) =

(3.4) (10^-14) (1.8) (10^28) =

(3.4) (1.8) (10^-14) (10^28) =

(6.12) (10^ (-14+28)) =

(6.12) (10^14)

answer is first option
