    作业：求算式 155×(4.2+5+4.2+3.4)+1/2×52.7×3.8×7.6+1/2×59.033×3×6 的值.
    题型：数学计算
    解:
          155×(4.2+5+4.2+3.4)+1/2×52.7×3.8×7.6+1/2×59.033×3×6
        =155×16.8+1/2×52.7×3.8×7.6+1/2×59.033×3×6
        =2604+1/2×52.7×3.8×7.6+1/2×59.033×3×6
        =2604+0.5×52.7×3.8×7.6+1/2×59.033×3×6
        =2604+26.35×3.8×7.6+1/2×59.033×3×6
        =2604+100.13×7.6+1/2×59.033×3×6
        =2604+760.988+1/2×59.033×3×6
        =2604+760.988+0.5×59.033×3×6
        =2604+760.988+29.5165×3×6
        =2604+760.988+88.5495×6
        =2604+760.988+531.297
        =3364.988+531.297
        =3896.285
    答案:155×(4.2+5+4.2+3.4)+1/2×52.7×3.8×7.6+1/2×59.033×3×6=3896.285
