25×36的简便计算? -
25x36 =25x4x9 =100x9 =900
简算:25x36等于900 =25×30+25×6 =750+150 =900
25x36 =25x4x9 =100x9 =900
简算:25x36等于900 =25×30+25×6 =750+150 =900
=(5×6)×(5×6)30×30 =900
解,原式=25×(30+6)25×30+25×6 =750+150 =900

25x36的简算过程25x36 =25x4x9 =100x9 =900
36可以分为4乘以9,25乘以4为100,所以36乘以25等于4乘以9乘以25等于900
25x36=多少? 用简便计算 -
回答:25x(4x9) =25x4x9 =100x9 =900
25x36 =(20+5)x36 =720+180 =900

巧用简便计算25×36 解题思路:不能进行简便运算的按顺序计算,简便运算核心是运用加法和乘法各种定律进行计算,计算出整数部分方便后续计算的过程解题过程:25×36 =25×6×6 =150×6 =900 存疑请追问,满意请采纳,
原式=5*5*6*6=(5*6)(5*6)30*30=900
