75乘以1/76乘以77简算
75乘以1/76乘以77简算

75乘以1/76乘以77简算
=（76-1）*1/76*(76+1)=(76²-1)*1/76=76-1/76=75又75/76

75乘以1/76乘以77
=75/76×（76+1）
=75/76×76+75/76×1
=75+75/76
=75又75/76

75× 1/76 ×77
=75 ×77 × 1/76
=（76-1） ×（76+1） × 1/76
=（76²-1）×1/76
=76²×1/76 -1×1/76
=76-1/76
=75又75/76

75×1/76×77
=75×1/76×（76+1）
=75×（1+1/76）
=75又75/76

75乘以1/76乘以77简算 77乘以77乘以1/76减1/76 77乘以77乘以1/76减1/76 75乘以76分之一乘以77如何简便计算 1乘以2乘以3+2乘以3乘以4+3乘以4乘以5+...+7乘以8乘以9 75分之1乘以80 (21乘以7分之3+7分之4乘以21)乘以4分之1=简算写得数:3/5乘以1/4,11/25乘以5/33,六乘以1/3乘以2/5,77/100乘以零乘以写得数:3/5乘以1/4,11/25乘以5/33,六乘以1/3乘以2/5,77/100乘以零乘以8/9,答案请写在纸上, =3乘以2乘以1,=4乘以3乘以2乘以1,=5乘以4乘以3乘以2乘以1,那么100!除以99! 1乘以2乘以3乘以4乘以5乘以.100积有几个零 77乘以13加255再乘以999加510的简便算法,1992乘以584减380分之204加584再乘以1991,减143分之1的简便运算999乘以274加6274的简便运算.975乘以0.25加9又4分之3再乘以76减9.75的简便运算.越快越好. 0.25乘以1.25乘以8乘以40=简算 1.1乘以四分之一+0.25乘以5.8+3.1乘以四分之一简算 512乘以81+11乘以825+637乘以19 简算 512乘以81+11乘以825+637乘以19 简算 13乘以2.7乘以1乘以1.33等于多少计算2007乘以2008乘以2009乘以2010+1 计算2007乘以2008乘以2009乘以2010+1
