6a+13a6x-28-2.5x30.58a-(5a+8)(5x+7)-(4x+0.18) 6a+13a6x-28-2.5x30.58a-(5a+8)(5x+7)-(4x+0.18) 请化简下列各题6a+13a6x-28-2.5x+30.58a-(5a+8)(5x+7)-(4x+0.18) (2x²-x-1)³=a+a1x+a2x²+a3x³+a4x^4+a5x^5+a6x^6 则a1+a3+a5=?急 39/25X30/13怎么约分? (-36)x(-9/5)x5/6x(-3)怎么写?还有(1/6-1/5+2/15+1/30)x30 25%x+3=3分之2*6 18-5%x=12.8 2x30%x=18.4 (4/3+6/1)除以24/1 (5/4-10/3)x30 以上两题怎么简算 若(2x+1)^6=a0+a1x+a2x^2+a3x^3+a4x^4+a5x^5+a6x^6,求:-a0+a1-a2+a3-a4+a5-a6 (2x-1)^6=a6x^6+a5x^5+a4x^4+a3x^3+a2x^2+a1x+1,则a6+a5+a4+a3+a2+a1=? 已知(3x-1)^7=a7x^7+a6x^6+a5x^5……a1x+a0,则a7+a6+a5……a1+a0的值是多少? 已知(1-2x)^7=a0+a1x+a2x^2+a3x^3+a4x^4+a5x^5+a6x^6+a7x^7,则a1+a2+a3+a4+a5+a6+a7 若(2x^2-x-1)^3=a0+a1x+a2x^2+a3x^3+a4x^4+a5x^5+a6x^6,则a1+a3+a5= =ao+a1x+a2x^2+a3x^3+a4x^4+a5x^5+a6x^6,那么ao+a1+a2+a3+a4+a5+a6=?,a0+a2+a4+a6=?、 一个字母的又下角有个数字是什么意思比方说这道题(我不会的,顺便帮我解)a又边的数字是在a的右下角若(2x+1)^6=a0+a1x+a2x^2+a3x^3+a4x^4+a5x^5+a6x^6,那么-a0+a1-a2+a3-a4+a5-a6=__ 数学计算.速度.【27.36-9.36÷0.9】【85x0.7+6x85-0.85x30】解方程:【5x-5分之12=5分之28】【x÷18%=30】【8(x-3.5)=44】【60%x+2.5=40】 设(3x-1)的7次方=a7x的7次方+a6x的6次方+a5x的5次方+……+a1x+a0,试求a0+a2+a4+a6的值a7是右下角有个小7,就是第7个a,如此类推>.a7x的7次方,是x的7次方,与a7无关,a7是个代数 二项式定理(2x-1)^6=a0+a1x+a2x^2+a3x^3+a4x^4+a5x^5+a6x^6则a0+a1+a2+a3+a4+a5的值为(2x-1)^6=a0+a1x+a2x^2+a3x^3+a4x^4+a5x^5+a6x^6则a0+a1+a2+a3+a4+a5的值为!
