Question

Tính giá trị các biểu thức sau

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

Answer 1

Ta có : \(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=\frac{3^{10}.\left(11+5\right)}{3^9.16}=\frac{3^{10}.16}{3^9.16}=3\)3

Answer 2

\(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=\frac{3^{10}.\left(11+5\right)}{3^9.2^4}\) \(=\frac{3^{10}.16}{3^9.2^4}=\frac{3^{10}.2^4}{3^9.2^4}=3\)

Answer 3

Tớ đánh sai nha, đáp án là 3.

Answer 4

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

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

                               \(=3\)

_Học tốt nha_

Answer 5

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

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

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

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