200:2*540+460:10

Let's solve the expression step by step:

1. First, divide 200 by 2: $$200 : 2 = 100$$
2. Then, multiply the result by 540: $$100 \cdot 540 = 54000$$
3. Next, divide 460 by 10: $$460 : 10 = 46$$
4. Finally, add the results: $$54000 + 46 = 54046$$

So, the final answer is:

Answer: 54046
