Answer:
The correct answer is 32x - 4
Step-by-step explanation:
1) Simplify 6 + 2 to 8.

2) Simplify 8 + 8 to 16.

3) Simplify 2x × 16 to 32x.

<u>Therefor</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>32x</u><u> </u><u>-</u><u> </u><u>4</u>.
Since they have the same base we can just add all the exponents
-3+ 10= 7
keep the base so the answer is
12^7
