355 = ( 311)5 = 1771475
535 = ( 57)5 = 781255
Vì 177147>78125 => 1771475 > 781255 => 355 > 535
Hk tốt
3\(^{55}\)= ( 3\(^{11}\))\(^5\)= 177147\(^5\)
5\(^{55}\)= ( 5\(^7\))\(^5\)= 78125\(^5\)
Vì 177147 > 78125\(\Rightarrow\)177147\(^5\)> 78125\(^5\) \(\Rightarrow\)3\(^{55}\)> 5\(^{55}\)
Vậy: 3\(^{55}\)> 5\(^{55}\)
4300 và 3400
ta có 4300=43.100=(43)100=64100
3400=34.100=(34)100=81100
vì 64<81 nên 64100<81100
hay 4300<3400
Ta có : \(4^{300}=4^{3.100}=\left(4^3\right)^{100}=64^{100}\)
\(3^{400}=3^{4.100}=\left(3^4\right)^{100}=81^{100}\)
Vì 64 < 84
Nên .................
a )
2100+2100= 2100(1+1) =2100.2 = 2100+1= 2101
b)
3100+3100 = 3100(1+1) = 2.3100
3101= 3100.3
ta thấy 3. 3100 > 2.3100 Vậy 3101 > 3100+3100
c) 20177012 > 20172337.3 >>> 80002337
70122017 < 80002337
suy ra: 20177012 >>> 70122017
Ta có: 1/3^400 = 1/3^(4x100) = (1/3^4)^100 = 1/81^100
1/4^300 = 1/4^(3x100) = (1/4^3)^100 = 1/64^100
Vì 1/81^100 < 1/64^100
hay 1/3^400 < 1/4^300.
nhớ duyệt nhé .
3400 = ( 34 )100 = 81100
4300= (43) 100 = 64100
Suy ra : 3400 > 4300
Click mình click lại
a) Ta có :
164 = ( 42 )4 = 48 < 411
=> 164 < 411
b) Ta có :
8115 = ( 92 )15 = 930 > 920
=> 8115 > 920
c) Ta có :
250 = ( 25 )10 = 3210 > 2510 = ( 52 )10 = 520
=> 250 > 520
d) Ta có :
545 = ( 53 )15 = 12515 > 12115 = ( 112 )15 = 1130
=> 545 > 1130
e) Ta có :
7300 = ( 72 )150 = 49150 < 64150 = ( 43 )150 = 4450
=> 7300 < 4450
mk sẽ tíck cho những bn trả lời cho mk( nhank giúp mk, mk cần gấp!)
4 ^300 và 3 ^400
ta có 4 ^300= 4 ^3.100= 4^3 ( 100) = 64 ^ 100
3 ^ 400= 3 ^4.100= ( 3^4) ^100 = 81 ^100
Vì 64 < 81 nên 4 ^ 300 < 3 ^ 400
= nhau k mik nha
mình nghĩ 3 400 lớn hơn vì số 3 đc nhân nhiều lần, bạn biết cách tính mẹo 2 số đó ko chỉ mình với
We don't talk anymore
We don't talk anymore
We don't talk anymore

We don't laugh anymore
What was all of it for
Ohh, we don't talk anymore, we used to do...
I just heard you found the one, you been looking
You been looking for
I wish I would have known that wasn't me
Cause even after all this time
I still wonder
Why I can't move on
Just the way you did so easily
Don't wanna know
Kinda dress you're wearing tonight
If he's holdin onto you so tight
The way I did before
I overdosed
Shoulda known your love was a game
Now I can't get you out of my brain
Ohh, it's such a shame
That we don't talk anymore
We don't talk anymore
We don't talk anymore
we used to do
We don't laugh anymore
What was all of it for?
Oh, we don't talk anymore
we used to do..
