Exponent Questions

1. If you had (2^6 2^4)^3 would you first subtract the 2^6 2^4 using exponent laws to equal (2^2)^3 or multiply the 3 by the other to powers to equal
2^18 2^12. I know they both equal 2^6 but is there a certain way to start this?

2. Is there an exponent law if there is 2^12 + 2^6?

3. For the Img below. how can you simplify it further?

THX but now can someone help me w/ 3rd question now?

You have:

Notice all of the exponents are factors of 2. Thus, we may write it as:
