Please write a rational number mixed operation problem and write the calculation process. The problem should meet the following conditions at the same time: 1. It must contain five operations: addition, subtraction, multiplication, division and power 2. Divisor must be a fraction 3. The base of a power operation must be a negative fraction 4. The result is equal to 2010

2×（25× 12－25×2)÷(－1/2)^2＋10=50×(12-2)÷(1/4)+10=50×10×4+10=2010
