\(N=\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}=\frac{2^{12}.3^{15}+2^9.3^9.2^3.3.5}{2^{12}.3^{12}-2^{11}.3^{11}}=\frac{2^{12}.3^{15}+2^{12}.3^{10}.5}{2^{12}.3^{12}-2^{11}.3^{11}}=\frac{2^{12}.3^{10}\left(3^5+5\right)}{2^{11}.3^{11}\left(2.3-1\right)}\)
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 !
\(N=\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\)
\(N=\frac{4^6.9^5+6^9.120}{4^8.9^6-6^9.6^2}\)
\(N=\frac{36^5.4+36^4.6.6.20}{36^5.576-36^4.6.6.36}\)
\(N=\frac{36^5.4+36^5.20}{36^5.576-36^5.36}\)
\(N=\frac{36^5.\left(4+20\right)}{36^5.\left(576-36\right)}\)
\(N=\frac{36^5.24}{36^5.540}\)
\(N=\frac{24}{540}\)
\(N=\frac{2}{45}\)
Vậy \(N=\frac{2}{45}\)
