Question

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

Answer 1

TA CÓ

A=\(\dfrac{3^{10}.11+3^{10}.5}{3^9.2^4}=\dfrac{3^{10}.\left(11+5\right)}{3^9.2^4}=\dfrac{3^{10}.16}{3^9.16}=3\)

vậy A=3

chúc bạn học tốt

Answer 2

\(A=\dfrac{3^{10}.11+3^{10}.5}{3^9.2^4}=\dfrac{3^{10}\left(10+5\right)}{3^9.2^4}=\dfrac{3^{10}.15}{3^9.2^4}=\dfrac{3.15}{2^4}=\dfrac{45}{16}\)

Answer 3

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

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

\(A=\dfrac{3^{10}.16}{3^9.16}=\dfrac{3^{10}}{3^9}=3\)
