Question

so sánh:

Answer 1

\(243^7=\left(3^5\right)^7=3^{35}\\ 9^{10}\cdot27^5=3^{35}\)

Vậy \(243^7=9^{10}\cdot27^5\)

Answer 2

243^7=(3^5)^7=3^35

9^10*27^5=3^20*3^15=3^35

=>243^7=9^10*27^5

Answer 3

ta có :

`243^7 = 3^(5.7) = 3^35`

`9^10 . 27^5 = 3^(2.10) . 3^(3.5) = 3^20 . 3 ^15 =3^35 `

Vì /`3^35 = 3^35`

Hay `243^7 = 9^10. 27^5`
