Final answer:
To multiply numbers in scientific notation, multiply the coefficients and add the exponents. The final answer is 7.2 x 10^11.
Step-by-step explanation:
To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents.
In this case, (9.104) multiplied by (8.106) gives you (9 * 8) multiplied by (104+6).
So the result is 72 multiplied by 1010, which can be written in scientific notation as 7.2 x 1011.
