答案和解析
0.397+0.00397*3600-4.8*3.97+150*0.0397
=0.397+0.397*36-48*0.397+15*0.397
=0.397*(1+36+15-48)
=0.397*4
=1.588
4.4*18+0.56*165
=4.4*18+5.6*16.5
=4.4*18+5.6*(18-1.5)
=(4.4+5.6)*18-5.6*1.5
=180-8.4
=171.6
=0.397+0.397*36-48*0.397+15*0.397
=0.397*(1+36+15-48)
=0.397*4
=1.588
4.4*18+0.56*165
=4.4*18+5.6*16.5
=4.4*18+5.6*(18-1.5)
=(4.4+5.6)*18-5.6*1.5
=180-8.4
=171.6
