Answer 1

a)(3.8 ×1.75:10+1.02):100+0.4×2.6×2.6-0.1×0.1×0.1=
=(6.65:10+1.02):100+2.704-0.001=
=(0.665+1.02):100+2.703=
=1.685:100+2.703=
=0.01685+2.703=2.71985

b)0.2×(11.28+3.4:100×1.55):10+0.6×3×3-0.2×0.2×0.2×0.2=
=0.2×(11.28+0.034×1.55):10+5.4-0.0016=
=0.2×(11.28+0.0527):10+5.3984 =
=0.2×11.3327:10+5.3984 =
=0.2×1.13327+5.3984 =
=0.226654+5.3984 =5.625054
