作业：求算式 (2191.5×10^3)/(0.995×20479.8×215)+(1.0×144.4×10^6)/(1.05×2865986.06×(1-(0.8×2191.5)/1508080.55)×215) 的值.
题型：数学计算
解:
(2191.5×10^3)/(0.995×20479.8×215)+(1.0×144.4×10^6)/(1.05×2865986.06×(1-(0.8×2191.5)/1508080.55)×215)
=2191500/(0.995×20479.8×215)+(1.0×144.4×10^6)/(1.05×2865986.06×(1-(0.8×2191.5)/1508080.55)×215)
=2191500/4381141.215+(1.0×144.4×10^6)/(1.05×2865986.06×(1-(0.8×2191.5)/1508080.55)×215)
=2191500/4381141.215+144400000/(1.05×2865986.06×(1-(0.8×2191.5)/1508080.55)×215)
=2191500/4381141.215+144400000/(1.05×2865986.06×(1-1753.2/1508080.55)×215)
=2191500/4381141.215+144400000/(1.05×2865986.06×0.998837×215)
=2191500/4381141.215+144400000/646243896.286445
=0.500212+144400000/646243896.286445
=0.500212+0.223445
=0.723657
答案:(2191.5×10^3)/(0.995×20479.8×215)+(1.0×144.4×10^6)/(1.05×2865986.06×(1-(0.8×2191.5)/1508080.55)×215)=0.723657
