Tính giá trị biểu thức 

Answer 1

\(A=\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}.\left(13+65\right)}{2^8.104}=\frac{2^{10}.78}{2^8.104}=3\)

Answer 2

\(A=\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}\left(13+65\right)}{2^8.104}=\frac{2^{10}.78}{2^8.104}=\frac{2^2.78}{104}=\frac{2^2.2.39}{2^3.13}=\frac{2^3.39}{2^3.13}=3\)

Answer 3

\(A=\frac{2^{10}.13+2^{10}.65}{2^8.104}\)

\(=>A=\frac{2^{10}.\left(65+35\right)}{2^8.104}=\frac{2^{10}.78}{2^8.104}=3\)
