2/33+4/33+6/33+8/33~~~~~100/33
2/33+4/33+6/33+8/33~~~~~100/33
2/33+4/33+6/33+8/33~~~~~100/33
2/33+4/33+6/33+8/33~~~~~100/33
=(2+4+6+8+.+100)/33
=[(2+100)*50/2]/33
=50*51/33
=50*17/11
=850/11
答：
2/33+4/33+6/33+8/33+....+100/33
=(2/33)(1+2+3+4+...+50)
=(2/33)(1+50)*50/2
=2550/33
=850/11
2/33+4/33+6/33+8/33~~~~~100/33
2/33+4/33+6/33+8/33+10/33+14/33+16/33改写成乘法算式并计算
把33分之2+33分之4+33分之6+33分之8+33分之10+33分之14+33分之16改写成乘法算式并计算
33,
(1-0.95)*(2.2+1.2/0.25) 33/99(33+1)/(33+2)*(33-3)/(33+4)/(33+5)*(33-6)/./(33+35)
写出数列,33+2,33+6,33+12,33+20,33+30,的通项公式,
1/2*1/33+1/3*1/33+1/6*1/33-1/33简便算法
33/4/6*2表示什么意思
4/33X+4/33X+7=3/8(4/33X+4/33X+7)要一步步写出
33+33-1-32+4/2+2+3
33+33等于几
33题33题啊
简算 33乘99加33乘2减33
89*2/33+2/33,简算
33+56*8=?
计算:(+1.25)+(-33/8)
算术题...根号下(2+4/6根号33)+1根号下(2-4/6根号33)+1不好意思..是4/6次根号33外面
4/33×133用奥数来做
