Work: Calculate the value of equation (31.4-0.24*2)*(1.35-0.24*2)+(48.6-0.24*2)*(15.5-0.24*2)*2+(6.28-0.24*2)*(2.25-0.24*2)+(51.16-0.24*2)*(8.91-0.24*2) .
Question type: Mathematical calculation
Solution:
(31.4-0.24*2)*(1.35-0.24*2)+(48.6-0.24*2)*(15.5-0.24*2)*2+(6.28-0.24*2)*(2.25-0.24*2)+(51.16-0.24*2)*(8.91-0.24*2)
=30.92*(1.35-0.24*2)+(48.6-0.24*2)*(15.5-0.24*2)*2+(6.28-0.24*2)*(2.25-0.24*2)+(51.16-0.24*2)*(8.91-0.24*2)
=30.92*0.87+(48.6-0.24*2)*(15.5-0.24*2)*2+(6.28-0.24*2)*(2.25-0.24*2)+(51.16-0.24*2)*(8.91-0.24*2)
=30.92*0.87+48.12*(15.5-0.24*2)*2+(6.28-0.24*2)*(2.25-0.24*2)+(51.16-0.24*2)*(8.91-0.24*2)
=30.92*0.87+48.12*15.02*2+(6.28-0.24*2)*(2.25-0.24*2)+(51.16-0.24*2)*(8.91-0.24*2)
=30.92*0.87+48.12*15.02*2+5.8*(2.25-0.24*2)+(51.16-0.24*2)*(8.91-0.24*2)
=30.92*0.87+48.12*15.02*2+5.8*1.77+(51.16-0.24*2)*(8.91-0.24*2)
=30.92*0.87+48.12*15.02*2+5.8*1.77+50.68*(8.91-0.24*2)
=30.92*0.87+48.12*15.02*2+5.8*1.77+50.68*8.43
=26.9004+48.12*15.02*2+5.8*1.77+50.68*8.43
=26.9004+722.7624*2+5.8*1.77+50.68*8.43
=26.9004+1445.5248+5.8*1.77+50.68*8.43
=26.9004+1445.5248+10.266+50.68*8.43
=26.9004+1445.5248+10.266+427.2324
=1472.4252+10.266+427.2324
=1482.6912+427.2324
=1909.9236
Answer:(31.4-0.24*2)*(1.35-0.24*2)+(48.6-0.24*2)*(15.5-0.24*2)*2+(6.28-0.24*2)*(2.25-0.24*2)+(51.16-0.24*2)*(8.91-0.24*2)=1909.9236
