Question

8 mũ 10+4 mũ 10 phần 8 mũ 4+4 mũ 11

Answer 1

\(\frac{8^{10}+4^{10}}{8^4+4^{11}}\)

\(=\frac{\left(2^3\right)^{10}+\left(2^2\right)^{10}}{\left(2^3\right)^4+\left(2^2\right)^{11}}\)

\(=\frac{2^{30}+2^{20}}{2^{12}+2^{22}}\)

\(=\frac{2^{20}.\left(2^{10}+1\right)}{2^{12}.\left(2^{10}+1\right)}\)

\(=\frac{2^{20}}{2^{12}}\)

\(=2^8=256\)
