46x57+23x86 简便运算 怎么写??? -
46x57+23x86=23x2x57+23x86=23x(2x57+86)=23x200=4600
46x57+23x86简便运算=46x57+46x43 =46x(57+43)46x100 =4600
46x57+23x86=23x2x57+23x86=23x(2x57+86)=23x200=4600
46x57+23x86简便运算=46x57+46x43 =46x(57+43)46x100 =4600
46x57+23x86 =46x57+46x43 =46x(57+43)46x100 =4600
根据题意,计算过程如下,简便方法用到乘法分配律,46x57+23x86= 23×114+23×86 =23×(114+86)23×200 =4600

46*57+23*86 =46*57+46*43 =46*(57+43)46*100 =4600 希望我的回答能对你有帮助。
将46化为23X2,然后2X57=114,这样式子就变以成了23X114+23X86, 然后提取公因数23,括号内114+86=200,得到23X200=4600.

计算如下:46×57+23×86 =23×2×57+23×86 =23×114+23×86 =23×(114+86)=23×200 =4600
46*57+23*86 解题思路:将46拆为2×23后得23×2×57+23×86,便可对其进行提取公因式,得23×(2×57+86)即23×(114+86)即23×200=4600。解题步骤如下:解:原式=23×2×57+23×86 =23×(2×57+86)=23×(114+86)=23×200 =4600 一般地,如果多项式的各项有公因式,可以希望你能满意。
