1/4.4^x+3.4^(2-x)=832
Tim x biet rang:
a) 4/4^x + 3.4^2-x = 832
b) (3x - 2)^2002 = (3x - 2)^2004
c) /1 - 2x/ + x + 2 = 0
Tìm x biết :
\(a,2^x=\frac{8^4}{16^3}\)
\(b,\left(-2\right)^x=-4^6-8^5\)
\(c,4^x=4.4^{10}-3.4^{10}\)
\(d,4.3^{x-1}+2.3^{x+2}=4.3^6+2.3^9\)
\(e,\left(\frac{1}{3}+\frac{1}{6}\right).2^x+2^{x+1}=2^{12}+2^{10}\)
Ai nhanh mk sẽ tik nha , cám ơn m.n nhiều lắm
Tìm x
a) 1/4x4^x+3x4^2-x=832
b) l3x-2l^2004 = l3x-2l^2006
c) lx-5l-x=3
tìm x biết :(1.2+2.3+3.4+...+2017.2018)/(2018.2019.x)=1/(1+2)+1/(1+2+3)+....+1/(1+2+....+2018)
|x+1/1.2|+|x+1/2.3+|x+1/3.4|+....+|x+1/99.100|=100x. Tìm x
Tìm x :2^x+3.4^2=64
Tìm x : |x+1/1.2|+|x+1/2.3|+|x+1/3.4|+...+|x+2016.2017|=2017xGiúp mình với ! Cảm ơn
Tìm x, biết : 1.2 + 2.3 + 3.4 + ...... + 99.100 = \(2\frac{1}{5}x\) - 1
. là dấu nhân .
