\(a) 3^{200}=(3^2)^{100}=9^{100}\\2^{300}=(2^3)^{100}=8^{100}\)

Vì \(9^{100}>8^{100}\) nên \(3^{200}>2^{300}\)

\(b) 5^{40}=(5^4)^{10}=625^{10}\\3^{50}=(3^5)^{10}=243^{10}\)

Vì \(625^{10}>243^{10}\) nên \(5^{40}>3^{50}\)

#\(Toru\)

a> \(3^{200}\) và \(2^{300}\)

Ta có:\(3^{200}=3^{2.100}=\left(3^2\right)^{100}=9^{100}\)

          \(2^{300}=2^{3.100}=\left(2^3\right)^{100}=8^{100}\)

Vì 9>8 nên \(9^{100}>8^{100}\)

\(\Rightarrow\)\(3^{200}>2^{300}\)

b> \(5^{40}\) và \(3^{50}\)

Ta có:\(5^{40}=5^{4.10}=\left(5^4\right)^{10}=625^{10}\)

         \(3^{50}=3^{5.10}=\left(3^5\right)^{10}=243^{10}\)

Vì 625 > 243 nên \(625^{10}>243^{10}\)

\(\Rightarrow\)\(5^{40}>3^{50}\)

`3^200=(3^2)^100=9^100`.

`2^300=(2^3)^100=8^100`.

`=> 2^300 < 3^200`.

`b, 5^40=(5^4)^10=625^10.`

`3^50=(3^5)^10=243^10`.

`=> 5^40 > 3^50`.

Có: \(71^{50}=\left(71^2\right)^{25};37^{75}=\left(37^3\right)^{25}\)

Lại có: \(71^2< 72^2=\left(2\cdot36\right)^2=2^2\cdot36^2=4\cdot36^2< 36\cdot36^2=36^3< 37^3\)

Vậy \(71^{50}< 37^{75}\)

Ta có: \(71^{50}=\left(71^2\right)^{25}=5041^{25}\)

\(37^{75}=\left(37^3\right)^{25}=50653^{25}\)

mà \(5041^{25}< 50653^{25}\)

nên \(71^{50}< 37^{75}\)

71 ^ 50 > nhé

2³⁰⁰ = (2³)¹⁰⁰ = 8¹⁰⁰ và 3²⁰⁰ = (3²)¹⁰⁰ = 9¹⁰⁰ nên 2³⁰⁰ < 3²⁰⁰;

a) \(2^{300}=\left(2^3\right)^{100}=8^{100}\)

\(3^{200}=\left(3^2\right)^{100}=9^{100}>8^{100}\)

\(\Rightarrow2^{300}< 3^{200}\)

b) \(99^{20}=\left(99^2\right)^{10}=9801^{10}< 9999^{10}\Rightarrow99^{20}< 9999^{10}\)

c) \(3^{500}=\left(3^5\right)^{100}=243^{100}\)

\(7^{300}=\left(7^3\right)^{100}=343^{100}>243^{100}\)

\(\Rightarrow3^{500}< 7^{300}\)

Giải chi tiết giúp mình ạ~

\(\left(d\right):202^{303}=\left(202^3\right)^{101}=8242408^{101}>303^{202}=\left(303^2\right)^{101}=91809^{101}\)

\(\left(e\right):107^{50}=\left(107^2\right)^{25}=11449^{25}< 73^{75}=\left(73^3\right)^{25}=389017^{25}\)

Câu 1: 5110

Câu 2: 9999

Câu 3: 2384

a)5110

B)9999

c)2384

\(5110\)

\(9999\)

\(2384\)

`a)`

\(3^{200}\text{ và }2^{300}\)

\(3^{200}=\left(3^2\right)^{100}=9^{100}\)

\(2^{300}=\left(2^3\right)^{100}=8^{100}\)

Vì `9 > 8 => 9^100 > 8^100`

`=> 3^200 > 2^300`

\(27^{101}\text{ và }81^{35}\)

\(27^{101}=\left(3^3\right)^{101}=3^{303}\)

\(81^{35}=\left(3^4\right)^{35}=3^{140}\)

Vì `303 > 140 => 3^303 > 3^140`

`=> 27^101 > 81^35`

`c)`

\(2^{332}\text{ và }3^{223}\)

\(3^{223}>3^{222}=\left(3^2\right)^{111}=9^{111}\)

Vì `9 > 8 => 9^111 > 8^111`

`=> 2^332 < 3^223.`

a: 3^200=9^100

2^300=8^100

mà 9>8

nên 3^200>2^300

b: 27^101=3^303

81^35=3^140

mà 303>140

nên 27^101>81^35

c: 2^332<2^333=8^111

3^223>3^222=9^111

mà 9>8

nên 3^223>8^111>2^332
