[1/1 Formula]
Work: Calculate the value of equation 0.075*((4.2+3.5+0.2)*(4.2+1.6+0.2)+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.21))*2 .
Question type: Mathematical calculation
Solution:
0.075*((4.2+3.5+0.2)*(4.2+1.6+0.2)+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.21))*2
=0.075*(7.9*(4.2+1.6+0.2)+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.21))*2
=0.075*(7.9*6+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.21))*2
=0.075*(7.9*6+5.6*(2.7+2.1+0.21))*2
=0.075*(7.9*6+5.6*5.01)*2
=0.075*75.456*2
=5.6592*2
=11.3184
Answer:0.075*((4.2+3.5+0.2)*(4.2+1.6+0.2)+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.21))*2=11.3184
