Work: Calculate the value of equation (20+18.5×1.5+19.8×3.8+19.4×1.8+18.8×1.2)×0.49-2×17×√0.49 .
Question type: Mathematical calculation
Solution:
(20+18.5×1.5+19.8×3.8+19.4×1.8+18.8×1.2)×0.49-2×17×√0.49
=180.47×0.49-2×17×√0.49
=180.47×0.49-2×17×0.7
=88.4303-2×17×0.7
=88.4303-34×0.7
=88.4303-23.8
=64.6303
Answer:(20+18.5×1.5+19.8×3.8+19.4×1.8+18.8×1.2)×0.49-2×17×√0.49=64.6303
