23.42+46.84×0.5378×1/4+0.5378×46.84×0.75-8×46.84×0.125×0.5378等于多少?请用简便算
23.42+46.84×0.5378×1/4+0.5378×46.84×0.75-8×46.84×0.125×0.5378等于多少?请用简便算
用分配律：23.42+(1/4+0.75-8×0.125)×46.84×0.5378
=23.42+0
=23.42
23.42+46.84×0.5378×1/4+0.5378×46.84×0.75-8×46.84×0.125×0.5378
=23.42+0.5378+[0.25*46.84+46.84*0.75]-46.84*(8*0.125)*0.5378
=23.42+0.5378*46.84-46.84*0.5378
=23.42
运用乘法分配律做：提出相同的数
23.42+46.84×0.5378×1/4+0.5378×46.84×0.75-8×46.84×0.125×0.5378
=23.42+46.84×0.5378×(1/4+0.75-8×0.125)
=23.42+46.84×0.5378×0
=23.42+0
=23.42
23.42+46.84×0.5378×1/4+0.5378×46.84×0.75-8×46.84×0.125×0.5378/是÷号结果是23.42，
23.42+46.84×0.5378×1/4+0.5378×46.84×0.75-8×46.84×0.125×0.5378等于多少?请用简便算
计算：46.84*0.5378*1/4+0.5378*46.84*0.75
46.84×0.5378×四分之一+0.5378×46.84×0.75-0.78 请用简便算法,
