1.342xx10^121.342×1012

Explanation:

(6.1xx10^5)(2.2xx10^6)(6.1×105)(2.2×106)

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

6.1xx2.2xx10^5xx10^66.1×2.2×105×106

Next, multiply the two numbers

13.42xx10^5xx10^613.42×105×106

Next, add the exponents base 1010 units

13.42xx10^(5+6)13.42×105+6

13.42xx10^(11)13.42×1011

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

1.342xx10^121.342×1012
