8.612 x 10⁶

Step-by-step explanation:

 Given problem:

                (8.60×10⁶) + (1.2×10⁴)

Solve by the process of scientific notation;

Solution:

            (8.60×10⁶) + (1.2×10⁴)

 Adjust the exponent so that they are of the same value;

     8.6 x 10⁶ = 860 x 10⁴

So;

     (860 x 10⁴) +  (1.2×10⁴)  = (860 + 1.2) x 10⁴

                                           = 861.2 x 10⁴

or

       8.612 x 10⁶

the correct answer is the second option
