Answer: 9+c
======================================================
Step-by-step explanation:
3 to the 2nd power is the same as writing 3^2 in shorthand
3^2 = 3 squared
When we square a number, we're multiplying it by itself (having 2 copies total of the number). Think of a square with side length 3 units. Its area is 3^2 = 3*3 = 9 square units.
From here, we add on c to get our answer 9+c. We don't know the value of c, so we cannot evaluate further. Also, 9 and c are not like terms so we cannot combine them.
