$\frac{8^{10}+4^{10}}{8^4+4^{10}}$$=\frac{\left(2^3\right)^{10}+\left(2^2\right)^{10}}{\left(2^3\right)^4+\left(2^2\right)^{10}}$$=\frac{2^{30}+2^{20}}{2^{12}+2^{20}}$$=\frac{2^{20}.\left(2^{10}+1\right)}{2^{12}.\left(1+2^8\right)}$$=\frac{2^8.\left(2^{10}+1\right)}{1+2^8}$$=\frac{262400}{257}$Câu trả lời: $\frac{8^{10}+4^{10}}{8^4+4^{10}}$$=\frac{\left(2^3\right)^{10}+\left(2^2\right)^{10}}{\left(2^3\right)^4+\left(2^2\right)^{10}}$$=\frac{2^{30}+2^{20}}{2^{12}+2^{20}}$$=\frac{2^{20}.\left(2^{10}+1\right)}{2^{12}.\left(1+2^8\right)}$$=\frac{2^8.\left(2^{10}+1\right)}{1+2^8}$$=\frac{262400}{257}$

Mai Trung Nguyên · Answer

$\frac{8^{10}+4^{10}}{8^4+4^{10}}=\frac{2^{30}+2^{20}}{2^{12}+2^{20}}=\frac{2^{12}.\left(2^{18}+2^{10}\right)}{2^{12}.\left(1+2^{10}\right)}\frac{2^{18}+2^{10}}{2^{10}+1}$Câu trả lời: $\frac{8^{10}+4^{10}}{8^4+4^{10}}=\frac{2^{30}+2^{20}}{2^{12}+2^{20}}=\frac{2^{12}.\left(2^{18}+2^{10}\right)}{2^{12}.\left(1+2^{10}\right)}\frac{2^{18}+2^{10}}{2^{10}+1}$
