Final answer:
After multiplying 3.1 x 10 and 2.2 x 10^7 together, the result is 6.82 x 10^8, which does not match any of the given options, indicating a possible error in the provided choices.
Step-by-step explanation:
The question asks for the product of two numbers in scientific notation: (3.1 x 10) and (2.2 x 107). First, we multiply the coefficients (3.1 and 2.2), which gives us 6.82. Then, we add the exponents (1 from 101 and 7 from 107) since we are multiplying powers of 10, giving us 101+7 or 108. The result is thus 6.82 x 108. However, as none of the provided options matches this result, it seems there might be an error in the choices given or in the initial question provided by the student.
