Ta có : \(2^{70}=\left(2^7\right)^{10}=128^{10}\)
\(3^{51}>3^{50}=\left(3^5\right)^{10}=243^{10}\)
Mà : \(128^{10}< 243^{10}\)\(\rightarrow2^{70}< 3^{50}< 3^{51}\)
\(\rightarrow2^{70}< 3^{51}\)
Chúc bạn hk tốt
Ta có:
2^70=(2^7)^10=128^10
3^51=3^50.3=(3^5)^10.3=243^10.3
Vì 128^10<243^10.3<=>2^70<3^51
Vậy 2^70 < 3^51
