$1.342xx10^12$

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

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

$1.342xx10^12$
