`x+1-10+900=100000`

`x-9+900=100000`

`x=100000-900+9`

`x=99100+9`

`x=99109`

Vậy `x=99109`

Vậy 

(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!)

11111111111 k nha thanh

100000x100=10000000

100000:100=1000

Kb vs mk nhé!!

100000X100 = 10000000

100000: 100 = 1000

100000 x 100 = 10000000

100000 : 100 = 1000

\(a,5^{2x-1}=25\\ \Leftrightarrow5^{2x-1}=5^2\\ \Leftrightarrow2x-1=2\\ \Leftrightarrow2x=3\\ \Leftrightarrow x=\dfrac{3}{2}\)

\(b,3^{x+1}=9^{2x+1}\\ \Leftrightarrow3^{x+1}=3^{4x+2}\\ \Leftrightarrow x+1=4x+2\\ \Leftrightarrow3x=-1\\ \Leftrightarrow x=-\dfrac{1}{3}\)

\(c,10^{1-2x}=100000\\ \Leftrightarrow10^{1-2x}=10^5\\ \Leftrightarrow1-2x=5\\ \Leftrightarrow2x=-4\\ \Leftrightarrow x=-2\)

x < 1 /1000  => x = 0

x > 9.999   => x = 10 ; x = 11 .......

x > 197/100000   => x = 1 ; x =  2 ......

Chắc vậy đó.

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

\(x< \frac{1}{1000}< =>x=0\)

\(x>9,999< =>x=9;x=10;...\)

\(x>\frac{197}{100000}< =>x=1;x=2;x=3;...\)

\(100000=56743+x\)

\(x=100000-56743\)

\(x=43257\)

= 43257 bạn nhé

100000=56743+x

x+56743 =100000

x = 100000-56743 

x = 43257
