Work: Calculate the value of equation (31.2+0.87)/4+(4.65×2.65)/(2.675×2.675×4)+(5.57×3.2)/(3.2×3.2×4) .
Question type: Mathematical calculation
Solution:
(31.2+0.87)/4+(4.65×2.65)/(2.675×2.675×4)+(5.57×3.2)/(3.2×3.2×4)
=32.07/4+(4.65×2.65)/(2.675×2.675×4)+(5.57×3.2)/(3.2×3.2×4)
=32.07/4+12.3225/(2.675×2.675×4)+(5.57×3.2)/(3.2×3.2×4)
=32.07/4+12.3225/28.6225+(5.57×3.2)/(3.2×3.2×4)
=32.07/4+12.3225/28.6225+17.824/(3.2×3.2×4)
=32.07/4+12.3225/28.6225+17.824/40.96
=8.0175+12.3225/28.6225+17.824/40.96
=8.0175+0.430518+17.824/40.96
=8.0175+0.430518+0.435156
=8.448018+0.435156
=8.883174
Answer:(31.2+0.87)/4+(4.65×2.65)/(2.675×2.675×4)+(5.57×3.2)/(3.2×3.2×4)=8.883174
