222333=2223.111=(2223)111=666111
333222=3332.111=(3332)111=666111
vì 666111=666111
=>222333=333222
222333 = (2.111)333
= 2333 . 111333
= 23.111 . 1113.111
= (23)111 . (1113)111
= 8111 . (1112.111)111
= 8111 . (1112)111 .111111
= 888111 . (1112)111
333222=(3.111)222
=3222 . 111222
=32.111 . 1112.111
= (32)111 . (1112)111
= 9111 . (1112)111
Mà 888111 . (1112)111 > 9111 . (1112)111 nên 222333 > 333222

TA CÓ : (222^3)^111=(2.111)^3=2^3.111^3=8.111^3=8.111.111^2=888.111^2
(333^2)^111=(3.111)^2=3^2.111^2=9.111^2
9<888
888.111^2>9.111^2
vậy 222^333>333^222

\(2^{100};1024^8\)
\(2^{100}\text{Giữ nguyên }\)
\(1024^8=\left(2^{10}\right)^8=2^{18}\)
\(2^{100}>2^{18}=2^{100}>1024^8\)
\(222^{333};333^{222}\)
\(222^{333}=\left(222^3\right)^{111}\)
\(333^{222}=\left(333^2\right)^{111}\)
\(222^3=2^3.111^3=16.111^3\)
\(333^2=3^2.111^2=9.111^2\)
\(16.111^4>9.111^2\)
\(222^{333}>333^{222}\)
Nếu làm như vậy thì bạn sẽ là người làm đúng !

222333 = 2223.111 = ( 2223 )111 = 10941048111
333222 = 3332.111 = ( 3332 )111 = 110889111
mà 10941048111 > 110889111 => 222333 > 333222
Ta có : \(222^{333}=222^{3.111}=\left(222^3\right)^{111}\)
\(333^{222}=333^{2.111}=\left(333^2\right)^{111}\)
Ta so sánh : \(222^3\) và \(333^2\)
\(222^3=\left(2.111\right)^3=2^3.111^3=8.111^3=888.111^2\)
\(333^2=\left(3.111\right)^2=3^2.111^2=9.111^2\)
Vì \(888>9\) \(\Rightarrow\) \(888.111^2>9.111^2\)
\(\Rightarrow\) \(222^3< 333^2\) \(\Rightarrow\) \(222^{333}< 333^{222}\)

a) 3150 = 32 . 75 = ( 32 ) 75 = 975
2225 = 23 . 75 = ( 23 ) 75 = 875
Vì 9 > 8 nên 975 > 875 hay 3150 > 2225
b) 201620 = 20162 . 10 = ( 20162 ) 10
2016201610 = giữ nguyên
ta thấy hai lũy thừa đã cùng số mũ là 10 , giờ ta so sánh hai cơ số
20162 = 2016 . 2016
20162016 = 2016 . 10001
Vì 2016 < 10001 nên 20162 < 20162016 hay 201620 < 2016201610
c) 222333 = 2223 . 111 = ( 2223 ) 111
333222 = 3332 . 111 = ( 3332 ) 111
2223 = ( 2 . 111 ) 3 = 23 . 1113 = 8 . 1113
3332 = ( 3 . 111 ) 2 = 32 . 1112 = 9 . 1112
=> 222333 > 333222

\(a,17< 23\Rightarrow333^{17}< 333^{23}\\ b,2007< 2008\Rightarrow2007^{10}< 2008^{10}\\ c,\left(2008-2007\right)^{2009}=1^{2009}=1^{1999}=\left(1998-1997\right)^{1999}\)
a )
Ta có :
\(125^3=\left(5^3\right)^3=5^9\)
Do \(5^9< 5^{10}\)
\(\Rightarrow125^3< 5^{10}\)
b )
Ta có :
\(222^{333}=\left(222^3\right)^{111}\)
\(333^{222}=\left(333^2\right)^{111}\)
So sánh : \(222^3;333^2\)
Lại có :
\(222^3=\left(2.111\right)^3=2^3.111^3=8.111^3=8.111.111^2=888.111^2\)
\(333^2=\left(3.111\right)^2=3^2.111^2=9.111^2\)
Do \(888.111^2>9.111^2\)
\(\Rightarrow222^3>333^2\)
\(\Rightarrow\left(222^3\right)^{111}>\left(333^2\right)^{111}\)
\(\Rightarrow222^{333}>333^{222}\)
~ Ủng hộ nhé
a,
Ta có :
1253 = ( 53 )3 = 53.3 = 59 < 510
=> 510 > 1253
