分解因式计算:0.582*8.69+1.236*8.69+24.78*0.869+0.5704*86.9
分解因式计算:0.582*8.69+1.236*8.69+24.78*0.869+0.5704*86.9
分解因式计算:0.582*8.69+1.236*8.69+24.78*0.869+0.5704*86.9
0.582*8.69+1.236*8.69+24.78*0.869+0.5704*86.9
=0.582*0.869*10+1.236*0.869*10+24.78*0.869+0.5704*0.869*100
=0.869*(5.82+12.36+24.78+57.04)
=0.869*100
=86.9
0.582*8.69+1.236*8.69+24.78*0.869+0.5704*86.9=（0.508+1.236+2.478+5.704）*8.69=86.9
=0.582*8.69+1.236*8.69+2.478*8.69+5.704*8.69
=8.69*(0.582+1.236+2.478+5.704) = 8.69*10=86.9 (将0.869变成8.69，所以前面的要缩小10倍，变成2.478，后面的和这个一个道理）
