\(9^8:3^2\)
\(=\left(3^2\right)^8:3^2\)
\(=3^{16}:3^2\)
\(=3^{14}\)
9^8:3^2
= (3^2)^8 : 3^2
= 3^16 : 3^2
=3^14
\(9^8:3^2=\left(3^2\right)^8:3^2=3^{16}:3^2=3^{\left(16-2\right)}\)

\(9^8:3^2=\left(3^2\right)^8:3^2=3^{16}:3^2=3^{16-2}=3^{14}\)
\(9^8\div3^2\)
\(=\left(3^2\right)^8:3^2\)
\(=3^{16}:3^2\)
\(=3^{14}\)
Làm:

Viết kết quả phép tính dưới dạng một lũy thừa :
9^8 : 3^2
= ( 3^2 ) ^8 : 3^2
= 3^16 : 3^2
= 3^16-2
= 3^14
Vậy 9^8 : 3^2 = 3^14
