解:25X16X125等于( 50000 )
∵已知需求出25X16X125等于多少
∴25 X 16 X 125
= 25 × (4 × 4)× 125
= 25 × 4 × 4 × 125
= (25 × 4)× (4 × 125)
= 100 × 500
= 50000
答:25X16X125等于50000
很高兴回答你的问题,解答过程如下:
25x16×125
=25x(2×8)×125
=(25x2)x(8×125)
=50x1000
=50000
满意请采纳!
简便算法:
25x16×125
=25x(2×8)×125
=(25x2)x(8×125)
=50x1000
=50000
25x16x125简便方法
=25x2x8x125
=25x2x(8x125)
=50x1000
=50000
16分为4*4 125分为25+100 原式=25*4*4*(100+25)=100*4*100+100*4*25
=40000+10000
=50000
