2x+2x+1+2x+2+...+2x+2020=2x+2024-8
2x+2x+1+2x+2+2x+3+...+2x+2021=22025-8
2x + 2x + 1 + 2x + 2=960 - 2x + 3
2x + 2x+1 + 2x+2 +......+2x+2021 =22026 -16
2x + 2x+1 + 2x+2 +......+2x+2021 =22026 -16
2x+2x+1+2x+2+...+2x+2015=22019- 8
2x + 2x+1+ 2x+2 + .... + 2x+2021 = 22026 - 16
Tìm x:
2x + 2x+1 + 2x+2 + 2x+3 = 480
