\(a,\left(3^2\cdot5^2\cdot4^3\right):\left(8\cdot3^2\right)\)
\(=\frac{3^2\cdot5^2\cdot4^3}{8\cdot3^2}\)
\(=\frac{3^2\cdot5^2\cdot2^6}{2^3\cdot3^2}\)
\(=5^2\cdot2^3\)
\(=25\cdot8=200\)
\(b,\left(2^{10}\cdot13+2^9\cdot130\right):\left(2^8\cdot104\right)\)
\(=\frac{2^{10}\cdot13+2^9\cdot130}{2^8\cdot104}\)
\(=\frac{2^9\cdot\left(2\cdot13+130\right)}{2^8\cdot2^3\cdot13}\)
\(=\frac{2^9\cdot156}{2^{11}\cdot13}\)
\(=\frac{2^9\cdot2^3\cdot3\cdot13}{2^{11}\cdot13}\)
\(=\frac{2^{12}\cdot3\cdot13}{2^{11}\cdot13}\)
\(=2.3=6\)
