Question

Hay so sanh 2³⁰ va 3²⁰

Answer 1

Ta có:\(2^{30}=\left(2^3\right)^{10}=8^{10}\)

\(3^{20}=\left(3^2\right)^{10}=9^{10}\)

Vì 9>8\(\Rightarrow9^{10}>8^{10}\Rightarrow3^{20}>2^{30}\)

Answer 2

Ta có:

\(2^{30}=\left(2^3\right)^{10}=8^{10}\)

\(3^{20}=\left(3^2\right)^{10}=9^{10}\)

\(\Rightarrow8^{10}< 9^{10}\Rightarrow2^{30}< 3^{20}\)

k mik nha

Answer 3

2^30=2^(3.10)=(2^3)^10=8^10

            320=3^(2.10)=(3^2)^10=9^10

Vì 8 < 9 nên 8¹⁰ < 9¹⁰

Vậy 2³⁰ < 3²⁰

h nha

Answer 4

Ta có:
\(2^{30}=\left(2^3\right)^{10}=8^{10}< 9^{10}=\left(3^2\right)^{10}=3^{20}\)

cHỖ CUỐI LÀ 3^20 NHÁ.

Vậy.....

Answer 5

ta có 2x 30=60 ; 3x20=60 

vì 60=60 nên 2^{30 =}3²⁰

Answer 6

2\(^{30}\)=1073741824

3\(^{20}\)=3486784401

vậy 1073731824<3486784401

\(\Rightarrow\)2\(^{30}\)>3\(^{20}\)

Answer 7

2³⁰ = ( 2³)¹⁰ = 8¹⁰

3²⁰= (3²)¹⁰ = 9¹⁰

vì 9¹⁰ >  8¹⁰ => 2³⁰ <3²⁰

Answer 8

\(2^{30}\)và \(3^{20}\)

Ta có :

\(2^{30}=\left(2^3\right)^{10}=8^{10}\)

\(3^{20}=\left(3^2\right)^{10}=9^{10}\)

Vì \(8^{10}< 9^{10}\), nên \(2^{30}< 3^{20}\)
