Answer 1

#)Giải :

\(A=\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=\frac{3^{10}\left(11+5\right)}{3^9.2^4}=\frac{3^{10}.2^4}{3^9.2^3}=3\)

Answer 2

\(A=\frac{3^{10}.11+3^{10}.5}{3^9.2^4}\)

\(A=\frac{3^{10}\left(11+5\right)}{3^9.2^4}\)

\(A=\frac{3^{10}.16}{3^9.2^4}\)

\(A=\frac{3^{10}.2^4}{3^9.2^4}\)

\(A=3\)
