Question

[Trần Văn Thành]

Rút gọn:

\(N=\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\)

Answer 1

[Thanh Hằng Nguyễn]

\(N=\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}=\frac{2^{12}.3^{15}+2^9.3^9.2^3.3.5}{2^{12}.3^{12}-2^{11}.3^{11}}=\frac{2^{12}.3^{15}+2^{12}.3^{10}.5}{2^{12}.3^{12}-2^{11}.3^{11}}=\frac{2^{12}.3^{10}\left(3^5+5\right)}{2^{11}.3^{11}\left(2.3-1\right)}\)

Answer 2

[Nguyễn Thị Ngọc Ánh]

cho mk sửa lại xíu:

\(\frac{2^{12}.3^{10}\left(1+5\right)}{2^{11}.3^{11}.5}=\frac{2.6}{3.5}=\frac{12}{15}=\frac{4}{5}\)

mk sai xíu. hihi, học tốt nhé !
