Answer 2

a)(3.8×1.75÷10+1.02)÷100+0.4×2.6²-0.1³=
(6.65÷10+1.02)÷100+0.4×2.6²-0.1³=
(0.665+1.02)÷100+0.4×6.76-0.001=
1.685÷100+0.4×6.76-0.001=
0.01685+2.704-0.001=
2.72085-0.001=2.71985
b)0.2×(11.28+3.4÷100×1.55)÷10+0.6×3²-0.2∧4=
0.2×(11.28+0.034×1.55)÷10+0.6×9-0.0016=
0.2×(11.28+0.0527)÷10+5.4-0.0016=
0.2×(11.3327)÷10+5.4-0.0016=
0.2×11.3327÷10+5.4-0.0016=
2.26654÷10+5.4-0.0016=
0.22654+5.4-0.0016=5.625054
