Question

Cần gấp ạ

Answer 1

F=\(-\dfrac{1}{3}\)

Answer 2

\(F=\dfrac{2^{10}\cdot3^8-2\cdot2^9\cdot3^9}{2^{10}\cdot3^8+2^8\cdot3^8\cdot2^2\cdot5}=\dfrac{2^{10}\cdot3^8\left(1-3\right)}{2^{10}\cdot3^8\left(1+5\right)}=\dfrac{-2}{6}=-\dfrac{1}{3}\\ \Rightarrow\left|F\right|=\dfrac{1}{3}\left(B\right)\)
