Answer: The answer is 13,841,287,201
Step-by-step explanation:
You start with the equation that's in the parenthese which is 7^6, and the answer is 117,649. Then you're left with 117,649^2, so you solve for that which is 13,841,287,201. I'm not sure if this is what you're looking for but I hope this can help you.
