Question

so sánh \(3^{4000}v\text{à}\)\(9^{2000}\) bằng hai cách

Answer 1

C1: \(3^{4000}=\left(3^2\right)^{2000}=9^{2000}\)

=> \(3^{4000}=9^{2000}\)

C2: \(9^{2000}=\left(3^2\right)^{2000}=3^{4000}\)

=> \(3^{4000}=9^{2000}\)

Answer 2

C1: Ta có : \(3^{4000}=\left(3^2\right)^{2000}=9^{2000}\)

Vậy \(3^{4000}=9^{2000}\)

C2: Ta có : \(9^{2000}=\left(3^2\right)^{2000}=3^{4000}\)

Vậy \(3^{4000}=9^{2000}\)

Answer 3

Ta có: \(9^{2000}=\left(3^2\right)^{2000}=3^{4000}\)

\(\Rightarrow3^{4000}=9^{2000}\)

~~~

Ta có: \(3^{4000}=3^{2.2000}=\left(3^2\right)^{2000}=9^{2000}\)

\(\Rightarrow3^{4000}=9^{2000}\)

P/S: Thế có đc xem là 2 cách không ? :v
