√225*6/3+9/3

Let's solve the expression step by step:

1. First, calculate the square root of 225: \(\sqrt{225} = 15\).

2. Then, multiply that result by 6: \(15 * 6 = 90\).

3. Now, divide by 3: \(90 / 3 = 30\).

4. Next, calculate \(9 / 3\): \(9 / 3 = 3\).

5. Finally, add the results from steps 3 and 4: \(30 + 3 = 33\).

So, the final result is \(33\).
