x^3 - 9x^2=x^3 -9x^2+2x -3
giup e ak=((
giup minh voi
\(\left[x-1\right]^{x+2}=\left[x-1\right]^{x+4}\)
cho x thoa man dang thuc 3/4+1/4/x=2/5.vay 7x=
giup minh voi
Chung minh da thuc Q(x) = x^4 + 3x^2 + 1 khong co nghiem voi moi gia tri cua x
chung minh rằng
x^3+1964x chia het cho 24 voi x chẵn
x^4-4x^3-4x^2+16x chi9a het cho 24 voi x chẵn
x^4+6x^2 - 7 chia het cho 32 voi x lẻ
a,|x-3| - | 2x-4| = 0
b, |3x-2| = x-1
c, |4-3x| = 2x+1
d, |4-2x| +|x+1| =6
giup minh voi
x-1/5 = y+4/-3= z-2 va x - 5y + z = 18
Giup minh voi nha may ban
tim x biet: |x-3|+|5-x|+2|x-4|=2 AI GIAI GIUP MINH VOI
Tim x, y, z biet
a ) |x-3,5|+ |x+5|=0
b) |x-1| + (y+1)^2 + |z-1|=0
c) ( x-1/3)^2 + (y-2)^2+ (z-1)^2 be hon hoac bang 0
d)(x-z)^2+ (y+x)^2 + (z+1/4)^2 =0
Cac ban giup minh voi minh can gap lam
