7.2x102 =7.2x(100+2)=7.2x100+7.2x2 =720+14.4 =734.4
100×7.83+2×7.83=783+15.66 所以结果是798.66
75×102-75×2简算 -
75×102-75×2 =75×(102-2)=75×100 =7500
简化成10×100=1000

简算102×76 -
=100×76+2× 76=7,752
解:102×87等于(8874 )∵已知需求出102×87等于多少X × (Y + Z) X × Y + X × Z ∴102 × 87 = (100 + 2)× 87 = 100 × 87 + 2 × 87 = 8700 + 174 = 8874 答:102×87等于8874
