Work: Calculate the value of equation ((2.4*2.8+6.5*2.8+2.5*2.8)*2+(1.2*2.1)+0.9*2.1*6+0.9)*2 .
Question type: Mathematical calculation
Solution:
((2.4*2.8+6.5*2.8+2.5*2.8)*2+(1.2*2.1)+0.9*2.1*6+0.9)*2
=(31.92*2+(1.2*2.1)+0.9*2.1*6+0.9)*2
=(31.92*2+2.52+0.9*2.1*6+0.9)*2
=78.6*2
=157.2
Answer:((2.4*2.8+6.5*2.8+2.5*2.8)*2+(1.2*2.1)+0.9*2.1*6+0.9)*2=157.2
