Question

Answer 1

= \(\dfrac{3^{12}-3^{12}.4}{3^{12}.4+3^{12}.2}\) = \(\dfrac{3^{12}\left(1-4\right)}{3^{12}\left(4+2\right)}\) = \(\dfrac{-3}{6}\) = -2

Đúng thì like giúp mik nha bạn. Thx bạn nhìu

 

Answer 2

b) \(\dfrac{3^{12}-3^{10}.36}{3^{12}.4+3^{11}.6}\) 

\(=\dfrac{3^{12}-3^{10}.3^2.2^2}{3^{12}.2^2+3^{11}.2.3}\) 

\(=\dfrac{3^{12}-3^{12}.2^2}{3^{12}.2^2+3^{12}.2}\)

\(=\dfrac{3^{12}\left(1-2^2\right)}{3^{12}\left(2^2+2\right)}\) 

\(=\dfrac{1-4}{4+2}\) \(=\dfrac{-3}{6}\)  \(\dfrac{-1}{2}\)
