a,5mũ 36=(5mũ3)mũ12=125 mũ12
11^24=(11^2)12=121^12
vì 121<125 nên 5^36>11^24
b.Ta có : = (111.3)111.4 = ( 1114 . 34 )111=
= ( 111 . 4 )111.3 = ( 1113.43)111 =
Vì (1114.81)111 > ( 1113.64 )111 => 333444 > 444333
a. 1030 = ( 103 )10=100010
2100 = ( 210 )10=102410
Vì 100010<102410 nên 1030<2100
a) \(100-\left(3.5^2-2.3^3\right)\)
\(100-\left(75-52\right)=100-23=77\)
b)\(4.5^2-3.2^3+3^9:3^7\)
\(100-24+9=85\)
c) \(\left(392:7\right).2^3-2^3+2020^0\)
\(8\left(56-1\right)+1=441\)
d) \(\left(6^2+7^2+8^2+9^2+10^2\right)-\left(1^2+2^2+3^2+4^2+5^2\right)=275\)
(lười - thông cảm :(
Đây bạn ơi a,\(100-\left(3.5^2-2.3^3\right)=100-\left(75-54\right)\))=100-19=81
b,\(4.5^2-3.2^3+\frac{3^9}{3^7}=100-24+9=85\)
c,\(\left(392:7\right).2^3-2^3+2020^0=56.2^3-2^3+1=441\)
d,\(=\left(6^2-1^2\right)+\left(7^2-2^2\right)+\left(8^2-3^3\right)+\left(9^2-4^2\right)+\left(10^2-5^2\right)\)
=\(5.7+5.9+5.11+5.13+5.15=5\left(7+9+11+13+15\right)\)
=\(5.55=275\)

Bài 1:
a) 02002 < 02023
b) 20220 = 20230
c) 549 < 5510
d) ( 4 + 5 )3 > 42 + 52
đ) 92 - 32 > ( 9 - 3 )2
Bài 2:
a) 32 x 43 - 32 + 333
= 9 x 64 - 9 + 333
= 576 - 9 + 333
= 567 + 333
= 900
b) 5 x 43 + 24 x 5 + 410
= 5 x 64 + 24 x 5 + 1
= 5 x ( 64 + 24 ) + 1
= 5 x 88 + 1
= 440 + 1
= 441
c) 23 x 42 + 32 x 5 - 40 x 12023
= 8 x 16 + 9 x 5 - 40 x 1
= 128 + 45 - 40
= 133
Bài 1 :
a) \(0^{2002}=0;0^{2023}=0\Rightarrow0^{2002}=0^{2023}\)
b) \(2022^0=1;2023^0=1\Rightarrow2022^0=2023^0\)
c) \(54^9< 55^9;55^9< 55^{10}\Rightarrow54^9< 55^{10}\)
d) \(\left(4+5\right)^3>\left(4+5\right)^2;\left(4+5\right)^2>4^2+5^2\Rightarrow\left(4+5\right)^3>4^2+5^2\)
đ) \(9^2-3^2=81-9=82;\left(9-3\right)^2=6^2=36\Rightarrow9^2-3^2>\left(9-3\right)^2\)
