ok? ai nhanh tick

Answer 1

Ta có:

A=\(\frac{3^{10}.11+3^8.45}{3^9.16}\)

A=\(\frac{3^{10}.11+3^{10}.5}{3^9.16}\)

A=\(\frac{3^{10}.\left(11+5\right)}{3^9.16}\)

A=\(\frac{3^{10}.16}{3^9.16}\)

A=3

Answer 2

\(\frac{3^{10}.11+3^8.45}{3^9.16}\) 

=\(\frac{59049.11+6561.45}{19683.16}\) 

=\(\frac{649539+295245}{314928}\) 

=\(\frac{944784}{314928}\) 

=3
