3⁰ và 5⁸

3⁰ < 5⁸

a, \(4^{100}=\left(2^2\right)^{100}=2^{200}< 2^{202}\)

\(\Rightarrow\text{ }4^{100}< 2^{202}\)

b, \(3^0=1< 5^8\)

\(3^0< 5^8\)

c, \(\left(0,6\right)^0=1\)

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) \(9^2-3^2=81-9=82;\left(9-3\right)^2=6^2=36\Rightarrow9^2-3^2>\left(9-3\right)^2\)

Bài 2 :

a) \(3^2.4^3-3^2+333=3^2\left(4^3-1\right)+9.37=9.63+9.37=9\left(63+37\right)=9.100=900\)

b) \(5.4^3+24.5+41^0=20.4^2+20.6+1=20\left(16+6\right)+1=20.22+1=441\)

c) \(2^3.4^2+3^2.5-40.1^{2023}=8.16+9.5-40.1=128+45-40=128+5=133\)

\(2^{333}< 3^{222}\)

2 mũ 1000 > 12 mũ 1200

9 mũ 99 > 99 mũ 9

a, 12^1200 > 2^100 Vì cả cơ số lẫn số mũ đều lớn hơn

b, 9^99= (9^11)^9

Vì 9^11> 99 nêm 99^11^9> 99^9

Vậy 9^99> 99^9

a, 8¹⁴ và 9²¹= 8^2.7và 9^3.7

                  = (8²)⁷ và (9³)⁷

                  = 16⁷ và 21⁷

do 16<21 nên 16⁷<21⁷ hay 8¹⁴<9²¹

b,5⁴⁰ và 620¹⁰= 5^4.10 và 620¹⁰

                           = (5⁴)¹⁰ và 620¹⁰

                    = 20¹⁰ và 620¹⁰

do 20<620 nên 20¹⁰< 620¹⁰ hay 5⁴⁰<620¹⁰

8 mũ 2 chứ ko phải 8 nhân 2 nha bạn
