2014.|x-12|+(x-12)^2=2013.|12-x| . Tìm x
Rút gọn biểu thức: P=12−12(x:16−14)−2|3x−2|P=12−12(x:16−14)−2|3x−2|
a, x lớn hơn hoặc bằng 2323
b, x <23
(12/25)^x=(5/3)^-2-(-3/5)^4
(12/25)^x=144/625
(12/25)^x=(12/25)^2
=>x=2
Tìm x biết: 2014*/x-12/+[x-12]^2=2013*/12-x/
Tìm x biết : x+2/10^10+x+2/11^11=x+2/12^12+x+2/13^13
tim x biet (x+2)/10^10+(x+2)/11^11=(x+2)/12^12+(x+2)/13^13
tìm x sao cho x+2/10^10+x+2/11^11+x+2/12^12=x+2/13^13+x+2/14^14
(x+2/)10^10)+(x+2)/11^11)=(x+2)/12^12)+(x+2)/13^13)
Tim x:
2014./x-12/ + (x-12)^2= 2013.(12-x)
tim x biet x+2/10^10 = x+2/11^11=x +2/12^12=x+2/13^13
