`x+1-10+900=100000`
`x-9+900=100000`
`x=100000-900+9`
`x=99100+9`
`x=99109`
Vậy `x=99109`

(100000 - 3333 x X) x 100000 - 9999 = 1
=> (100000 - 3333 x X) x 10000 = 10000
=> 100000 - 3333 x X = 1
=> 3333 x X = 99999
=> X = \(\frac{33333}{1111}\)
(Tíck cho mìk vs nha!)

\(a,5^{2x-1}=25\\ \Leftrightarrow5^{2x-1}=5^2\\ \Leftrightarrow2x-1=2\\ \Leftrightarrow2x=3\\ \Leftrightarrow x=\dfrac{3}{2}\)
\(b,3^{x+1}=9^{2x+1}\\ \Leftrightarrow3^{x+1}=3^{4x+2}\\ \Leftrightarrow x+1=4x+2\\ \Leftrightarrow3x=-1\\ \Leftrightarrow x=-\dfrac{1}{3}\)
\(c,10^{1-2x}=100000\\ \Leftrightarrow10^{1-2x}=10^5\\ \Leftrightarrow1-2x=5\\ \Leftrightarrow2x=-4\\ \Leftrightarrow x=-2\)

x < 1 /1000 => x = 0
x > 9.999 => x = 10 ; x = 11 .......
x > 197/100000 => x = 1 ; x = 2 ......
Chắc vậy đó.
