Work: Calculate the value of equation ((0.2+0.4*2)*(1.35+2.1)+0.2*0.4*2-0.12*2.1-0.12*1.3*2)*3 .
Question type: Mathematical calculation
Solution:
((0.2+0.4*2)*(1.35+2.1)+0.2*0.4*2-0.12*2.1-0.12*1.3*2)*3
=(1*(1.35+2.1)+0.2*0.4*2-0.12*2.1-0.12*1.3*2)*3
=(1*3.45+0.2*0.4*2-0.12*2.1-0.12*1.3*2)*3
=3.046*3
=9.138
Answer:((0.2+0.4*2)*(1.35+2.1)+0.2*0.4*2-0.12*2.1-0.12*1.3*2)*3=9.138
