$\frac{2^{10}.13+2^{10}.65 }{2^{8}.104}$
=$\frac{2^{10}.(13+65)}{2^{8}.104 }$
=$\frac{2^{10}.78}{2^{8}.104 }$
=$\frac{2^{2}.39.2}{52.2}$
=$\frac{2^{2}.39}{52}$
=$\frac{2.2.39}{2.2.13 }$
=$\frac{39}{13}$
=3
Đáp án:
`3`
Giải thích các bước giải:
`\frac{2^{10}.13+2^{10}.65}{2^{8}.104}`
`=\frac{2^{10}(13+65)}{2^{8}.104}`
`=\frac{2^{10}.78}{2^{8}.104}`
`=\frac{2^{8}.2^{2}.78}{2^{8}.104}`
`=\frac{2^{8}.312}{2^{8}.104}`
`=312/104=3`
