tim x
a)3^x+3^x+3=756
b)(2x-3)^4=(2x-3)^6
tim x
a/ (5x -1)^6 =729
b/(2x+1)^3=0,001
c/(2x-3)^4=(2x-3)^6
d/(2x+1)^5=(2x+1)^2010
tim x,y,z biet x/4=y/3 . x/3=z/5 và 2x-3y=6
tinh so huu ti x
2/3x-3/12=4/5-(7/x-2)
2x-3/3+-3/2=5-3x/6-1/3
tim x
(x-1).(x-2)>0
2x-3<0
(2x-4).(9-3x)<0
moi nguoi giup minh nhe cam on nhieu
|(x+1/2).|2x-3/4||=2x-3/4 tim x biet
\(\left(2x-3\right)^4=\left(2x-3\right)^6\) tim x
moi nguoi hay chieu co giup em vs:
c,3(2x-1)-5(x-3)+6(3x-4)=24
d,2x(5-3x)+2x(3x-5)-3(x-7)=3
xin dc cam on trc ah! Day la bai tim x ah!
Tim x,y,z biet x/4=y/3 . x/3=z/5 và 2x - 3y + z=6
.Tim x:
1. /x+1/+/x+3/=5
2. /x+1/+/x-2/+/x+3/=6
3. /2x-3/+/2x-5/=2
4. /x-5/-/x-6/=1
5. 2*/x+2/+/4-x/=11
6. /x-1/+/4-x/=3
7. /2x+5/+/2x-3/=8
