Let's take these questions one step at a time.
1) 3^2 + 2^3
3^2 is the same as saying 3 * 3
3 * 3 = 9
2^3 is the same as saying 2 * 2 * 2
2 * 2 = 4 * 2 = 8
Now, let's add them together: 9 + 8 = 17
2) 2^4 - 3^2
2^4 is the same as saying 2 * 2 * 2 * 2
2 * 2 = 4 * 2 = 8 * 2 = 16
3^2 is the same as saying 3 * 3
3 * 3 = 9
Now, let's solve the problem.
16 - 9 = 7
And there you go!
