Question

\(\frac{-7^{5^{ }}.4^9}{^{-49.2^8^{ }}^{ }}\)Rút gọn phân số

Answer 1

\(=\frac{7^5.2^{18}}{7^2.2^8}=7^3.2^{10}\)

Answer 2

\(\frac{-7^5.4^9}{-49.2^8}\)

\(=\frac{-7^5.\left(2^2\right)^9}{-7^2.2^8}\)

\(=\frac{-7^5.2^{18}}{-7^2.2^8}\)

\(=7^3.2^{10}\)

Answer 3

\(\frac{-7^5.4^9}{-49.2^8}\)=\(\frac{-7^5.2^{18}}{-7^2.2^8}\)=\(7^3.2^{10}\)=343.1024=351232
