QUESTION: When combining like terms, do you add exponents?

Let's say you're adding 2^3 and 5^3. Would you're answer just be 7^3 or 7^6? I'm really confused about this an would really love if someone would help!

I just need to know if the exponents would look like 7^3 or 7^6?  Do I add the exponents or leave them alone?
