Work: Calculate the value of equation 0.589×(18.7×3.9+19×(9.2-3.9)+9.4×(3.9+6.7-9.2)+20)+10×(3.9+6.7-9.2)-53.722 .
Question type: Mathematical calculation
Solution:
0.589×(18.7×3.9+19×(9.2-3.9)+9.4×(3.9+6.7-9.2)+20)+10×(3.9+6.7-9.2)-53.722
=0.589×(18.7×3.9+19×5.3+9.4×(3.9+6.7-9.2)+20)+10×(3.9+6.7-9.2)-53.722
=0.589×(18.7×3.9+19×5.3+9.4×1.4+20)+10×(3.9+6.7-9.2)-53.722
=0.589×206.79+10×(3.9+6.7-9.2)-53.722
=0.589×206.79+10×1.4-53.722
=121.79931+10×1.4-53.722
=121.79931+14-53.722
=135.79931-53.722
=82.07731
Answer:0.589×(18.7×3.9+19×(9.2-3.9)+9.4×(3.9+6.7-9.2)+20)+10×(3.9+6.7-9.2)-53.722=82.07731
