\(\frac{2^{10}\cdot13+2^{10}\cdot65}{2^8\cdot104}\)
\(=\frac{2^{10}\cdot\left(13+65\right)}{2^8\cdot13\cdot8}\)
\(=\frac{2^{10}\cdot78}{2^8\cdot13\cdot8}\)
\(=\frac{2^{10}\cdot13\cdot2\cdot3}{2^8\cdot13\cdot2\cdot4}\)
\(=\frac{2^2\cdot3}{4}\)
\(=3\)
\(=\frac{2^{10}x\left(13+65\right)}{2^8x104}\)
\(=\frac{2^8x2^2x78}{2^8x104}\)
\(=\frac{4x78}{104}\)
\(=\frac{312}{104}=3\)
\(\frac{2^{10}.13+2^{10}.65}{2^8.104}\)
\(=\frac{2^{10}\left(13+65\right)}{2^8.13.2.4}\)
\(=\frac{2^{10}.78}{2^8.13.2.4}\)
\(=\frac{2^{10}.13.2.3}{2^8.13.2.4}\)
\(=\frac{2^2.3}{4}\)
\(=3\)
\(\frac{2^{10}.13+2^{10}.65}{2^8.104}\)
\(=\frac{2^{10}.\left(13+65\right)}{2^8.13.8}\)
\(=\frac{2^{10}.78}{2^8.13.8}\)
\(=\frac{2^{10}.13.2.3}{2^8.13.2.4}\)
\(=\frac{2^2.3}{4}\)
\(=3\)
