d = \(\frac{2^{10}.13+2^{10}.65}{2^8.65}\)
\(\Rightarrow\frac{2^{10}\left(13+65\right)}{2^8.65}\)
\(\Rightarrow\frac{2^{10}.78}{2^8.65}\Rightarrow\frac{2^2.78}{65}\Rightarrow\frac{24}{5}\)
d = \(\frac{2^{10}.13+2^{10}.65}{2^8.65}\)
\(\Rightarrow\frac{2^{10}\left(13+65\right)}{2^8.65}\)
\(\Rightarrow\frac{2^{10}.78}{2^8.65}\Rightarrow\frac{2^2.78}{65}\Rightarrow\frac{24}{5}\)
rút gọn A=
