=...........................................................................................................................................
`x+1-10+900=100000`
`x-9+900=100000`
`x=100000-900+9`
`x=99100+9`
`x=99109`
Vậy `x=99109`
x+1−10+900=100000x+1-10+900=100000
x−9+900=100000x-9+900=100000
x=100000−900+9x=100000-900+9
x=99100+9x=99100+9
x=99109x=99109
Vậy x=99109
x + 100000 = 2000000 : 10
x + 100 000 = 200 000 0 : 10
x + 100 000 = 200 000
x = 200 000 - 100 000
x = 100 000
tk mk nha mik tk lại
năm mới vui vẻ
x+100 000=2 000 000:10
x+100 000=200 000
x=200 000-100 000
x=100 000
k mi nhe
100000 x 10
Tính:
10*10=
100*100=
1000*1000=
10000*10000=
100000*100000=
1000000*1000000=
10000000*10000000=
\(10\cdot10=100\)
\(100\cdot100=10000\)
Tính:
10*10=100
100*100=10000
1000*1000=1000000
10000*10000=100000000
100000*100000=10000000000
1000000*1000000=1000000000000
10000000000*10000000000=100000000000000000000

k nha
10+10*10-100+100000=?
Giải các phương trình sau:
a) \({5^{2x - 1}} = 25\);
b) \({3^{x + 1}} = {9^{2x + 1}}\);
c) \({10^{1 - 2x}} = 100000\).
\(a,5^{2x-1}=25\\ \Leftrightarrow5^{2x-1}=5^2\\ \Leftrightarrow2x-1=2\\ \Leftrightarrow2x=3\\ \Leftrightarrow x=\dfrac{3}{2}\)
\(b,3^{x+1}=9^{2x+1}\\ \Leftrightarrow3^{x+1}=3^{4x+2}\\ \Leftrightarrow x+1=4x+2\\ \Leftrightarrow3x=-1\\ \Leftrightarrow x=-\dfrac{1}{3}\)
\(c,10^{1-2x}=100000\\ \Leftrightarrow10^{1-2x}=10^5\\ \Leftrightarrow1-2x=5\\ \Leftrightarrow2x=-4\\ \Leftrightarrow x=-2\)
15^1 + 10^10 - 100000 =
151 + 1010 - 100000 = 9999900015
15^1 + 10^10 - 100000 =15+10000000000-100000=9999900015
máy tính đâu còn hỏi
