\(B=\frac{(3\cdot4\cdot2^{16})}{11\cdot2^{13}\cdot4^{11}-16^9}\)
\(=\frac{(2^2)^2\cdot(2^{16})^2\cdot3^2}{2^{13}\cdot(2^2)^{11}\cdot11-(2^4)^9}\)
\(=\frac{2^4\cdot2^{32}\cdot3^2}{2^{13}\cdot2^{22}\cdot11-2^{36}}\)
\(=\frac{2^{36}\cdot3^2}{2^{35}\cdot11-2^{36}}\)
\(=\frac{2^{36}\cdot3^2}{2^{35}\cdot(11-2)}\)
\(=\frac{2^1\cdot3^2}{9}\)
\(=\frac{2\cdot3^2}{3^2}=2\)
