\(202^{303}\text{ và }303^{202}\)

Ta có:

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

\(303^{202}=303^{101\cdot2}=\left(303^2\right)^{101}\)

So sánh `202^3` và `303^2`, ta có:

`202^3 = (2*101)^3 = 2^3 * 101^3 = 8 * 101^3 = 8* 101^2 * 101 = 808*101^2`

`303^2 = (3*101)^2 = 3^2 * 101^2 = 9 * 101^2`

Vì `9 < 808 \Rightarrow 9*101^2 < 808*101^2`

`\Rightarrow`\(202^{303}>303^{202}\)

Vậy, \(202^{303}>303^{202}.\)

1+1=3

202^303 = 202^3x101= (202^3)^101=8242408^101

303^202 = 303^2x101= (303^2)^101=91809^101

vì 8242408^101> 91809^101

=> 202^303 > 303^202

vậy .. .

ủng hộ nhé

202³⁰³ lớn hơn .

202³⁰³ = (202³)¹⁰¹ = 8242408¹⁰¹ > 91809¹⁰¹ = (303²)¹⁰¹ =303²⁰²

ko sai đâu

404/303=4/3

4/3=4/3

2121/3535=21/35

31/35>21/35

Ta có :\(\frac{404}{303}\)= \(\frac{4}{3}\)nên \(\frac{404}{303}=\frac{4}{3}\)

Ta có : \(\frac{31}{35}\)giữ nguyên và \(\frac{2121}{3535}\)= \(\frac{21}{35}\)

Vậy \(\frac{31}{35}>\frac{21}{35}\)

Chúc bạn học giỏi !

\(202^{303}=\left(202^3\right)^{101}=\left(2^3.101^3\right)^{101}=\left(808.101^2\right)^{101}>\left(9.101^2\right)^{101}=\left(303^2\right)^{101}=303^{202}\)

Vậy \(202^{303}>303^{202}\)

a ) Ta có :

5³⁰ = ( 5³ )¹⁰ = 125¹⁰ 

MÀ 125¹⁰ > 3¹⁰ hay 5³⁰ > 3¹⁰

Vậy 5³⁰ > 3¹⁰

b ) TA CÓ :

2⁴ = 16

5³⁰³ = 5² . 5³⁰¹ = 25 . 5³⁰¹

Mà  25 . 5³⁰¹ > 16 Do đó 5³⁰³ > 2⁴

Vậy 5³⁰³ > 2⁴

c ) ( tương tự phần b )

Ta co : 202³⁰³ va 303²⁰²

=> 202³⁰³=(202²)¹⁰¹=40804¹⁰¹                     (1)

=>303²⁰²=(303³)¹⁰¹=27818127¹⁰¹             (2)

Tu (1) va (2) suy ra 202³⁰³<303²⁰²
