(16×98+11X)÷﹙16×x﹚=8
(16×98+11X)÷﹙16×x﹚=8
(16×98+11X)÷﹙16×x﹚=8
114 + 11x = 8 (16 * x)
114 + 11x = 128 * 8x
3x = 14
x = 14/3
(16×98+11X)÷﹙16×x﹚=8
2x,-4x²,8x³,-16x﹙x的4次方﹚.
(98+11x)/(x+16)=8 x=?
解方程:8x -4.5÷0.2=16 3(x+30)=6x+30 3-(5-2x)=x+273x-(67-84x)-14=76 15-(7-5X)=2X(11-3X) X+(X+10)+(x+8)=36×3 11×(4-x)+15×(4-X)=30
哪个x的值是方程的解?x÷6=0.3 (x=20,x=1.8) 43+x=60 (x=19x=105)接着上面的 9x-5x=16 (x=64 x=4) 3.8x-x=5.6 (x=2 x=2.8)
4X+16=6X-8,求X
(11X+98)/(16+X)=8
(x^2-4x)/x^2-8x+16
x的平方+( )x+16=(x+ )(x+8)
x+(3x-16)÷25%=10﹙x+1﹚x=? (请写出过程)
解方程X²+3X-[20÷﹙X²+3X﹚=8
4x+1.2×5=24.4 x-0.7x=2.1 8x+5x=2.6 (4x+5)÷2=4x+1.2×5=24.4 x-0.7x=2.18x+5x=2.6 (4x+5)÷2=17.52x-16=24
解方程.x÷0.4=8 x+0.6x=16 20÷x=60
分式混合运算:[﹙x²-16﹚/﹙x²+8x+16﹚]+[x/﹙x-4﹚]
(x²+4x)平方+8(x²+4x)+16
matlab解数值分析题p=(x-1)*(x-2)*(x-3)*(x-4)*(x-5)*(x-6)*(x-7)*(x-8)*(x-9)*(x-10)*(x-11)*(x-12)*(x-13)*(x-14)*(x-15)*(x-16)*(x-17)*(x-18)*(x-19)*(x-20)解为1,2,3……,20取多个非常小的数用软件工具求解方程p(x)+n*x^19=0,并
计算:(16x的立方-8x的平方+4x)÷(-2x)
先化简,再求值:[(x-2/x²+2x)-(x-1/x²+4x+4)]÷﹙x-4/x+2﹚,其中x²+2x-1=0.
