a) Ta có:

\(2^{300}=2^{3\cdot100}=\left(2^3\right)^{100}=8^{100}\)

\(3^{200}=3^{2\cdot100}=\left(3^2\right)^{100}=9^{100}\)

Mà: \(8< 9\)

\(\Rightarrow8^{100}< 9^{100}\)

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

b) Ta có:

\(3^{500}=3^{5\cdot100}=\left(3^5\right)^{100}=243^{100}\)

\(7^{300}=7^{3\cdot100}=\left(7^3\right)^{100}=343^{100}\)

Mà: \(243< 343\)

\(\Rightarrow243^{100}< 343^{100}\)

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

c) Ta có: 

\(8^5=\left(2^3\right)^5=2^{3\cdot5}=2^{15}=2\cdot2^{15}\)

\(3\cdot4^7=3\cdot\left(2^2\right)^7=3\cdot2^{2\cdot7}=3\cdot2^{14}\)

Mà: \(2< 3\)

\(\Rightarrow2\cdot2^{14}< 3\cdot2^{14}\)

\(\Rightarrow8^5< 3\cdot4^7\)

d) Ta có:

\(202^{303}=202^{3\cdot101}=\left(202^3\right)^{101}=8242408^{101}\)

\(303^{202}=303^{2\cdot101}=\left(303^2\right)^{101}=91809^{101}\)

Mà: \(8242408>91809\)

\(\Rightarrow8242408^{101}>91809^{101}\)

\(\Rightarrow202^{303}>303^{202}\)

2³⁰⁰ = ( 2³)¹⁰⁰ = 8¹⁰⁰

3²⁰⁰ = ( 3²)¹⁰⁰ = 9¹⁰⁰

vậy 8 mũ 100 < 9 mũ 100

nên 2 mũ 300 < 3 mũ 200

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

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

mà \(9^{100}>8^{100}\Rightarrow3^{200}>2^{300}\)

Vậy,.........

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

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

Vì\(8< 9\Rightarrow8^{100}< 9^{100}\Leftrightarrow2^{300}< 3^{200}\)

em khong biet thua chi chi hay ra toan lop 4 di chi

 \(I-2I^{300}vàI-4I^{500}\)

ta có I -2I ^300 = 2^300

I-4I^500= 4^500= 2^2^500= 2^1000

vậy I-4I mũ 500 lớn hơn

đó là câu mấy vậy THÙY dương

a) 2011 . 2013 = 2011 . ( 2012 + 1 ) = 2011 . 2012 + 2011

2012² = 2012 . 2012 = ( 2011 + 1 ) . 2012 = 2011 . 2012 + 2012

Vì 2011 . 2012 + 2011 < 2011 . 2012 + 2012 nên 2011 . 2013 < 2012²

(3+4)²=3²+4²

Vì 3²+4²=3²+4² nên (3+4)²=3²+4²

2³⁰⁰=(2³)¹⁰⁰=8¹⁰⁰

3²⁰⁰=(3²)¹⁰⁰=9¹⁰⁰

Vì 8¹⁰⁰<9¹⁰⁰ nên 2³⁰⁰<3²⁰⁰

a ) 2²⁰⁰<8³⁰⁰

b ) 25²⁰⁰>5³⁰⁰

c ) 4²¹<64⁷

a)\(8^{300}=\left(2^3\right)^{300}=2^{900}\)

Vì \(200< 900\Rightarrow2^{200}< 8^{300}\)

b)\(25^{200}=\left(5^2\right)^{200}=5^{400}\)

Vì \(400>300\Rightarrow25^{200}>5^{300}\)

c)\(64^7=\left(4^3\right)^7=4^{21}\)

Vì \(4^{21}=4^{21}\Rightarrow4^{21}=64^7\)

\(5^{200}=25^{100}\)

\(3^{300}=27^{100}\)

mà 25<27

nên \(5^{200}< 3^{300}\)

a) <

b) =

c) =

2³⁰⁰ và 3²⁰⁰

Ta rút thử thành 2³ và 3²

2³ = 2.2.2 = 8

3² = 3.3 = 9

Vì 2³ < 3² nên 2³⁰⁰ < 3²⁰⁰

Ta có :

2³⁰⁰ = (2³)¹⁰⁰ = 8¹⁰⁰

3²⁰⁰ = (3²)¹⁰⁰ = 9¹⁰⁰

Vì 8¹⁰⁰ < 9¹⁰⁰ nên 2³⁰⁰ < 3²⁰⁰
