Răspuns

1600:4:[3×70-(2×45-3²×2³×5×3:12):5³×2²+95×2]×12

400:[210-(90-9x8x5x3:12):125x4+95x2]x12

400:[210-(90-72x5x3:12):125x4+190]x12

400:[210-(90-360x3:12):125x4+190]x12

400:[210-(90-1080:12):125x4+190]x12

400:[210-(90-90):125x4+190]x12

400:(210-0:125x4+190)x12

400:(210-0+190)x12

400:400x12
