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

Vậy `x=99109`
x+1−10+900=100000x+1-10+900=100000

x=99109x=99109
Vậy x=99109
( 100000 - 3333 x X ) x 10000 -9999 = 1
(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 = \(\frac{33333}{1111}\)

KB nhé
100000x100=10000000
100000:100=1000
Kb vs mk nhé!!
100000X100 = 10000000
100000: 100 = 1000
Giải các phương trình sau:
a) \({5^{2x - 1}} = 25\);
b) \({3^{x + 1}} = {9^{2x + 1}}\);
c) \({10^{1 - 2x}} = 100000\).
\(a,5^{2x-1}=25\\ \Leftrightarrow5^{2x-1}=5^2\\ \Leftrightarrow2x-1=2\\ \Leftrightarrow2x=3\\ \Leftrightarrow x=\dfrac{3}{2}\)
\(b,3^{x+1}=9^{2x+1}\\ \Leftrightarrow3^{x+1}=3^{4x+2}\\ \Leftrightarrow x+1=4x+2\\ \Leftrightarrow3x=-1\\ \Leftrightarrow x=-\dfrac{1}{3}\)
\(c,10^{1-2x}=100000\\ \Leftrightarrow10^{1-2x}=10^5\\ \Leftrightarrow1-2x=5\\ \Leftrightarrow2x=-4\\ \Leftrightarrow x=-2\)
Tìm số tự nhiên x biết
x<1/1000
x>9,999
x>197/100000
x < 1 /1000 => x = 0
x > 9.999 => x = 10 ; x = 11 .......
x > 197/100000 => x = 1 ; x = 2 ......
Chắc vậy đó.
x<1/1000=>x=0
x>9,999=>x=10;x=11
x>197/100000=>x=1;x=2
Tìm số tự nhiên x biết
\(x< \frac{1}{1000}< =>x=0\)
\(x>9,999< =>x=9;x=10;...\)
\(x>\frac{197}{100000}< =>x=1;x=2;x=3;...\)
100000=56743+x
vậy x=?
\(100000=56743+x\)
\(x=100000-56743\)
\(x=43257\)
100000=56743+x
x+56743 =100000
x = 100000-56743
x = 43257
