Tính giá trị biểu thức: N=(3^10cdot 11+3^10cdot 5)/(3^8)cdot 2^(3cdot 6)cdot (3^4+3^4+3^4)

Ta có: N=\frac {3^{10}\cdot 11+3^{10}\cdot 5}{3^{8}\cdot 2^{3}\cdot 6}\cdot (3^{4}+3^{4}+3^{4}) =\frac {3^{10}(11+5)}{3^{8}\cdot 2^{3}\cdot 2\cdot 3}\cdot 3\cdot 3^{4} =\frac {3^{10}\cdot 16}{3^{9}\cdot 2^{4}}\cdot 3^{5} =\frac {3^{15}\cdot 2^{4}}{3^{9}\cdot 2^{4}} =3^{6}=\boxed{729}
