1.342xx10^12

Explanation:

(6.1xx10^5)(2.2xx10^6)

First, rewrite it so like terms are next to each other.

6.1xx2.2xx10^5xx10^6

Next, multiply the two numbers

13.42xx10^5xx10^6

Next, add the exponents base 10 units

13.42xx10^(5+6)

13.42xx10^(11)

Finally, move the decimal over one to the left and increase the power by one

1.342xx10^12
