Answer 1

        \(\frac{4^6.9^5+69.120}{8^4.31^2-6^{11}}\)

<=>-0,67

Answer 2

giải giúp mình chi tiết nhé!!!!!!

Answer 3

\(\frac{4^6.9^5+69.120}{8^4.31^2-6^{11}}=\frac{2^6.2^6.3^5.3^5+3.23.2^3.3.8}{\left(8^2\right)^2.31^2-\left(2.3\right)^{11}}\)

\(=\frac{2^6.2^6+3^5.3^5+3.23.2^3.3.8}{16^2.31^2-2^{11}.3^{11}}\)

\(=\frac{4^6.3^5.3^5+3.23.2^3.3.8}{\left(4^2\right)^2.31^2-2^{11}.3^{11}}\)

\(=\frac{4^6.3^5.3^5+3.23.2^3.3.8}{4^4.31^2-2^{11}.3^{11}}\)

Tới đây bạn tự làm nha.
