là bằng 1 nha
ahihihihihihihihihihihihihi
phải = 393 bạn nhá!!!!
Chúc cậu hk tố nha!!!
Ta có: \(\frac{7.4^5.3^{11}+2^{13}.9^5}{6^{10}+2^{12}.3^{10}}\)
\(=\frac{7.\left(2^2\right)^5.3^{11}+2^{13}.\left(3^2\right)^5}{\left(2.3\right)^{10}+2^{12}.3^{10}}\)
\(=\frac{7.2^{10}.3^{11}+2^{13}.3^{10}}{2^{10}.3^{10}+2^{12}.3^{10}}\)
\(=\frac{2^{10}.3^{10}\left(21+2^3\right)}{2^{10}.3^{10}\left(1+4\right)}\)
\(=\frac{29}{5}\)
hok tốt!!
