Question

Thực hiên phép tính:

a) 9⁸ : ( 27³ . 81² )

 

Answer 1

\(9^8:\left(27^3.81^2\right)=3^{16}:\left(3^9.3^8\right)=3^{16}:\left(3^{9+8}\right)=3^{16}:3^{17}=3^{-1}=\frac{1}{3}\)

Answer 2

\(9^8:\left(27^3.81^2\right)\)

\(=3^{16}:\left(3^9.3^8\right)\)

\(=3^{16}:3^{17}\)

\(=\frac{1}{3}\)

Answer 3

C1 : a) 9⁸ : ( 27³ . 81² )

= 43046721 : ( 19683 . 6561 )

= 43046721 : 129140163

=0,333333333
