Simplify the expression.

(6^2-3^) / 3

The expression can be simplified as follows:

(6^2 - 3^2) / 3

= (36 - 9) / 3

= 27 / 3

= 9

To simplify the expression (6^2-3^2) / 3, we need to evaluate the exponents first.

6^2 means 6 raised to the power of 2, which is 6 * 6 = 36.
Similarly, 3^2 means 3 raised to the power of 2, which is 3 * 3 = 9.

Now we can substitute these values back into the expression:
(36 - 9) / 3 = 27 / 3 = 9.

So, the simplified expression is 9.
