50 125x8x4简便方法计算

25x125x8x4=(25*4)*(125*8)=100*1000=100000 运用乘法交换律和乘法结合律

(50+125)*4简便计算=50*4+125*4=200+500=700.

(50+125)x4=50x4+125x4=2000+500=2500(50 125)x4=50000x4+125x4=200000+500=200500

(50十125)x4分解因式=50 x4+125x4=200+500=700

(50 +125)x4=50x4+125x4=200+500=700

25x125x8x4=(25x4)x(125x8)=100x1000=100000

乖乖算 原式=50x40+125x40=2000+5000=7000

=50X4X8+125X8X4 =200X8+1000X4 =1600+4000 =5600

你好,125*50*8*4=125X8X(50X4)=1000X200=200000

125*50*8*4=125x8x50x4=1000x200=200000
