Answer 2

\(A=\frac{\left(2^2\right)^5\cdot\left(3^2\right)^4-2\cdot69}{2^{10}\cdot3^8+6^8\cdot20}\)

\(A=\frac{2^{10}\cdot3^8-2\cdot3\cdot23}{2^{10}\cdot3^8+\left(2\cdot3\right)^8\cdot20}\)

\(A=\frac{6718464-1\cdot23}{6718464-6^7\cdot20}\)

\(A=\frac{6718464-23}{6718464-5598720}\)

\(A=\frac{6718441}{1119744}\)
