Question

[voduydat]

(2^8+8^3):(2^5.2^3)

Answer 1

[Duc Loi]

\(\left(\frac{2}{8}+\frac{8}{3}\right):\left(\frac{2}{5}.\frac{2}{3}\right)=\frac{35}{12}.\frac{5.3}{2.2}\)

\(=\frac{35.5.3}{3.4.4}=\frac{35.5}{16}=\frac{175}{16}.\)

Answer 2

[ﾟ°☆Žυƙα☆° ﾟ]

\(\left(2^8+8^3\right):\left(2^5.2^3\right)\)

\(=\left(2^8+2^9\right):2^8\)

\(=2^8\left(1+2\right):2^8\)
