If $a * b = a^b + b^a$, for all positive integer values of $a$ and $b$, then what is the value of $2 * 6$?
I need to apply the definition of the operation $*$ to the numbers 2 and 6. That means I need to evaluate $2^6 + 6^2$. I know that $2^6 = 64$ and $6^2 = 36$. So, $2 * 6 = 64 + 36$. I can add these two numbers to get the final answer.
