tim x thuoc Z biet:
|x-5|+x+3=16
||x+5|-4|=3
Cach lam nua nhe
Tim x thuoc \(Q\):
a) |5.(2x+3)|+|2.(2x+3)|+|2x+3|=16
b)|x2+|6x-2|| =x2+4
c)3x -|2x+1|=2
d)2.|x2+|x-1||=2x2+2
Cac anh chi CTV va cac ban giup mk nhe, mk dg can gap lem, nhanh len nhoa!! Tks truoc
tim x,y
xy=3(y-x)
nhanh len nhe cac ban
tim X biet
/x/=\(\frac{3}{4}vaX< 0\)
/\(X\)/=\(-1\frac{2}{5}\)
/x/=0.35 va X>0
giai giup mih nhe
1)tim x biet rang:
a)3^x-1=1/243
b)2^x+2^x+3=144
c)81^-2x.27x=9^5
2)tim tiep so ghang thu 5 cua day so sau:-1/a^2;2/a^3;-6/a^4;24/a^5;...
3)tim so tu nhien x biet :
a)4^x+4^x+3=4160
b)2^x-1+5.2^x-2=7/32
Tim x biet: (3/4x+5)-(2/3x-4)-(1/6x+1)=(1/3+4)-(1/3x-3)
tim x , biet :
1 ) 2017 - \ x - 2017 \ = x
2) -1/2 . ( 3x - 1 ) + 3/4 . ( 3-2x) = -3 . ( x/2 - 1 ) - ( 4/5) mu -1
tim x biet (2x-3)^2-4(x+1)^2=5
