Question

 Tính giá trị của biểu thức:  A = \(\frac{8^{10}+4^{10}}{8^4+4^{11}}\)

Answer 1

\(A=\frac{2^{30}+2^{20}}{2^{12}+2^{22}}=\frac{2^{12}.\left(2^{18}+2^8\right)}{2^{12}.\left(1+2^{10}\right)}=\frac{2^8.\left(2^{10}+1\right)}{1+2^{10}}=2^8\)

Answer 2

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

\(A=\frac{2^{12}\cdot\left(2^{18}+2^8\right)}{2^{12}\cdot\left(1+2^{10}\right)}\)

\(A=\frac{2^8\cdot\left(2^{10}+1\right)}{2^{10}+1}\)
