谢谢`我有急用``
76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)

谢谢`我有急用`` 76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
=76*(1/23-1/53)+23*(1/53+1/76)+53*(-1/23-1/53+1/53+1/76)
=76*(1/23-1/53)+[23*(1/53+1/76)+53*(1/53+1/76)]-53*(1/23+1/53)
=76*(1/23-1/53)+76*(1/53+1/76)-53*(1/23+1/53)
=76*(1/23+1/76)-53*(1/23+1/53)
=76/23+1-53/23-1
=1

这个直接算吧
(76/23-53/23)+(53/23-76/53)+(23/76+53/76)
=1-1+1
=1

76/23-76/53+23/53+23/76-53/23+53/76
=(76-53)/23-(76-23)/53+(23+53)/76
=1-1+1
=1

76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
=76/23-76/53+23/53+23/76-53/23+53/76
=(76/23-53/23)+(23/53-76/53)+(53/76+23/76)
=1-1+1
=1

将括号打开
76/23-76/53+23/53+23/76-53/23+53/76
=(76/23-53/23)-(76/53+23/53)+(53/76+23/76)
=1-1+1
=1

76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
=76/23 - 76/53 + 23/53 +23/76 -53/23 + 53/76
=(76-53)/23 -(76-23)/53 +(23+53)/76
=1-1+1
=1

1-1+1 =1

76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
=76*(1/23-1/53)+23*(1/53+1/76)+53*(-1/23-1/53+1/53+1/76)
=76*(1/23-1/53)+[23*(1/53+1/76)+53*(1/53+1/76)]-53*(1/23+1/53)
=76*(1/23-1/53)+76*(1/53+1/76)-53*(1/23+1/53)
=76*(1/23+1/76)-53*(1/23+1/53)
=76/23+1-53/23-1
=1
我这是最全面的!!

答案是 : 1
数字前后都相互抵消了。

直接装进去分子UNSDERSTAND?? 真傻问题

1

(76/23-53/23)+(53/23-76/53)+(23/76+53/76)
=1-1+1
=1
简单啊

1

(76/23-53/23)+(53/23-76/53)+(23/76+53/76)有错误,
分母不同怎能合并。
(76/23-53/23)+(23/53-76/53)+(23/76+53/76)
=1-1+1
=1

两种做法
1 打计算器
2 76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
=76/23-76/53+23/53+23/76-53/23+53/76
(然后把相同分母的数相加或相减)
=(76/23-53/23)+(23/53-76/53)+(23/76+53/76)
=1-1+1
=1

=1

小case,用计算器


76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
=(76/23-53/23)+(53/23-76/53)+(23/76+53/76)
=23/23+(-23/23)+76/76
=1+(-1)+1
=1-1+1
=1
希望是最佳答案!谢谢支持!

这些结果都对,建议你用软件,解这种数学题超简单
只要把东西输入进去,回车后就出现答案了
就是matlab,采纳我的意见,保证你以后计算方面再无忧虑

76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
=76/23-76/53+23/53+23/76-53/23+53/76
=(76/23-53/23)+(23/53-76/53)+(53/76+23/76)
=1-1+1

太”难”拉

1-1+1=1

(76/23-53/23)+(53/23-76/53)+(23/76+53/76)
=1-1+1

76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
一楼的学习应积极

76*(1/23-1/53)+23*(1/53+1/76)-53*(1/23-1/76)
=(76/23-53/23)+(53/23-76/53)+(23/76+53/76)
=23/23+(-23/23)+76/76
=1+(-1)+1
=1-1+1
