\(M=\frac{\left(2^3\right)^{20}+\left(2^2\right)^{20}}{\left(2^2\right)+\left(2^6\right)^5}\)
\(M=\frac{2^{60}+2^{40}}{2^{50}+2^{30}}\)
\(M=\frac{2^{40}\cdot2^{20}+2^{40}\cdot1}{2^{30}\cdot2^{20}+2^{30}\cdot1}\)
\(M=\frac{2^{40}\cdot\left(2^{20}+1\right)}{2^{30}\cdot\left(2^{20}+1\right)}\)
\(M=\frac{2^{40}}{2^{30}}\)
\(M=2^{40-30}\)
\(M=2^{10}\)
\(M=1024\)

\(M=\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
\(M=\frac{\left(2^3\right)^{20}+\left(2^2\right)^{20}}{\left(2^2\right)^{25}+\left(2^6\right)^5}\)
\(M=\frac{2^{60}+2^{40}}{2^{50}+2^{30}}\)
\(M=\frac{2^{40}\left(2^{20}+1\right)}{2^{30}\left(2^{20}+1\right)}\)
\(M=2^{10}\)
\(M=1024\)

\(M=\frac{8^{20}+4^{20}}{4^{25}+64^5}=\frac{4^{20}.\left(2^{20}+1\right)}{4^{25}+\left(4^3\right)^5}=\frac{4^{20}.\left(2^{20}+1\right)}{4^{25}+4^{15}}\)
\(=\frac{4^{20}.\left(4^{10}+1\right)}{4^{25}.\left(4^{10}+1\right)}=\frac{1}{4^5}=\frac{1}{1024}\)

Ta có: \(\frac{8^{20}+4^{20}}{4^{25}+64^5}=\frac{\left(2^3\right)^{20}+\left(2^2\right)^{20}}{\left(2^2\right)^{25}+\left(2^6\right)^5}=\frac{2^{60}+2^{40}}{2^{50}+2^{30}}\) \(=\frac{2^{40}.2^{20}+2^{40}}{2^{30}.2^{20}+2^{30}}=\frac{2^{40}.\left(2^{20}+1\right)}{2^{30}.\left(2^{20}+1\right)}\)\(=\frac{2^{40}}{2^{30}}=2^{10}=1024\)
