1) $\frac{3^{10}.11 + 3^{10}.5}{3^{9}.2^{4}}$
= $\frac{3^{10}.(11+5)}{3^{9}.(2^{2})^{2}}$
= $\frac{3^{10}.16}{3^{9}.4^{2}}$
= $\frac{3^{10}.4^{2}}{3^{9}.4^{2}}$
= $\frac{3^{10}}{3^{9}}$
= $3$
2) $\frac{2^{15} .2^{94}}{6^{6}.8^{3}}$
= $\frac{2^{(15+94)}}{2^{6}.3^{6}.(2^{3})^{3}}$
= $\frac{2^{109}}{3^{6}.2^{(9+6)}}$
= $\frac{2^{109}}{3^{6}.2^{15}}$
= $\frac{2^{94}}{3^{6}}$
