Work: Calculate the value of equation (20+18.5×1.3+19.8×4+19.4×2+18.8×1)×0.49-2×17×√0.49 .
Question type: Mathematical calculation
Solution:
(20+18.5×1.3+19.8×4+19.4×2+18.8×1)×0.49-2×17×√0.49
=180.85×0.49-2×17×√0.49
=180.85×0.49-2×17×0.7
=88.6165-2×17×0.7
=88.6165-34×0.7
=88.6165-23.8
=64.8165
Answer:(20+18.5×1.3+19.8×4+19.4×2+18.8×1)×0.49-2×17×√0.49=64.8165
