是这样的:x^5+x^4=x^3(x^2+x)=(x^2+x)[(x^3-1)+1]=(x^2+x)(x^3-1)+x^2+x=[x(x+1)(x-1)](x^2+x+1)+x^2+x=(x^3-x)
x(1+2+...+9)=x(9-8-7-...-1)x=0记得采纳啊
5x/64-x/25=15两边同时乘以1600得125x-64x=2400061x=24000x=24000/61很高兴为您解答,【学习宝典】团队为您答题.请点击下面的【选为满意回答】按钮.
每四项为一组,第一组x+x*x+x*x*x+x*x*x*x=x(x+x*x+x*x*x)=0以此类推结果为〇
(X+X)+(X-X)+(X*X)+(X/X)=1002X+0+X*X+1=1002X+X*X=99X(X+2)=99X=9再问:请问X(X+2)=99解为什么就等于9了呢没看懂再答:换成算术法你就明
X+X+X+X+X+X+100X=1690106x=1690x=845/53
乘以x-1,再除以x-1=(x-1)(x+1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)=(x^2-1)(x^2+1)(x^4+1)(x^8
设x1=4-√3,x2=4+√3,是方程X^2-8X+13=0的两根所以X1^2-8X1+15=2X^4-6X^3-2X^2+18X+23=(X+1)^2*(X^2-8X+13)+10=10所以原式=
当X=51a=51/10取整=5b=51/10取余=1X=10*1+5=15所以,运行结果为15
(x-22)+(x-24)+(x-27)+(x-20)=xx-22+x-24+x-27+x-20=x4x-93=x4x-x=933x=93x=31

1,应该是x是几次幂就有几个根吧,所以应该是7+2=9个2.-7.036622145,-6.489288572,-6.200988153,-4.734373320,-4.289168546,-2.77
