0.12+0.23+0.34+0.45+0.56+0.67+0.78+0.89,这是循环小数,最后一位循环.看得懂的来.0.12+0.23+0.34+0.45+0.56+0.67+0.78+0.89,
0.12+0.23+0.34+0.45+0.56+0.67+0.78+0.89,这是循环小数,最后一位循环.看得懂的来.
0.12+0.23+0.34+0.45+0.56+0.67+0.78+0.89,这是循环小数,最后一位循环.看得懂的来.
0.12+0.23+0.34+0.45+0.56+0.67+0.78+0.89,这是循环小数,最后一位循环.看得懂的来.
表述不清楚.“这是循环小数,最后一位循环.”写清楚点,不要随便省略.
(0.12+0.23+0.34)×(0.23+0.34+0.45)-(0.12+0.23+0.34+0.45)×(0.23+0.34)
(0.12+0.23+0.34)*(0.23+0.34+0.45)-(0.12+0.23+0.34+0.45)*(032+034)简便计算
0.12+0.23+0.34+0.45+0.56+0.67+0.78+0.89=?
(1+0.23+0.34)*(0.23+0.34+0.45)-(1+0.23+0.34+0.45)*(0.23+0.34)简便运算
(1+0.23+0.34)×(0.23+0.34+0.45)-(1+0.23+0.34+0.45)×(0.23+0.34)
0.12+0.23+0.34+0.45+0.56注意!都是循环的,例如0.12的12循环,0.23的23循环
求解(1+0.12+0.23)*(0.12+0.23+0.34)-(1+0.12+0.23+0.34)*(0.12+0.23)=?
简便运算 (1+0.12+0.23)x(0.12+0.23+0.34)-(1+0.12+0.23+0.34)x(0.12+0.23)
(1+0.12+0.23)*(0.12+0.23+0.34)-(1+0.12+0.23+0.34)*(0.12+0.23)=
(1+0.12+0.23)×(0.12+0.23+0.34)- (1+0.12+0.23+0.34)×(0.12+0.23).
(1+0.12+0.23)X(0.12+0.23+0.34)-(1+0.12+0.23+0.34)X(0.12+0.23)=?
(1+0.12+0.23)乘(0.12+0.23+0.34)_(1+0.12+0.23+0.34)乘(0.12+0.23)
0.12+0.23+0.34+0.45+0.56+0.67+0.78注意是循环小数,循环节在第二位
0.12+0.23+0.34+0.45+0.56答案是几 注:都是循环小数,第二位开始
0.12+0.23+0.34+0.45+0.56+0.67+0.78注意是循环小数,循环节在第二位 《2》
简便运算(1+0.12+0.23)X(0.12+0.23+0.34) - (1+0.12+0.34)X(0.12+0.23)
(0.12+0.23+0.34)*(0.23+0.34+0.45)-(0.12+0.23+0.34+0.45)这是题目,看我打字辛苦的份上帮帮我
(1+0.12+0.23)x(0.12+0.23+0.34)-(1+0.12+0.23+0.34)x(0.12+0.23)等于几?用简便方法计算!
