(12/5)^10*(-5/3)^11*(1/2)^22
第10 3 4 5 8 9 11 12题!
3/10+(4/11)-(6/5)-(-12/7)
2 2 5 10 7 21 3 12 11( )
用因式分解证明:5^12-4*5^11+10*5^10能被3整除
谁能告诉我这100个数字里 12各有几个12,12,3,12,12,11,12,10,12,9,7,12,8,12,5,10,11,5,11,7,11,10,11,11,3,11,11,11,12,12,12,12,2,2,12,4,12,12,12,12,12,12,9,12,9,12,12,10,12,12,12,8,11,11,11,11,1,12,12,10,4,12,12,9,12,12,12,12,12,8,12,5,12,12
1*2*3+2*3*4+3*4*5+5*6*7+.10*11*12
1*2*3+2*3*4+3*4*5+5*6*7+.10*11*12
(1)12^13(3^10*4^11) (2) (5^4*3^3-5^3*3^2+5^2*3)/15
5分之12乘11分之10
5分之12×11分之10 是
5 10 11 12怎么算24
x+5/8=11/12 10/11-x=2/3(x是未知数)
