rút gọn biểu thức a=5.(2^2.3^2)^9.(2^2)^6-2.(2^2.3)^14.3^4/5.2^28.3^18-7.2^29.3^18
\(=\dfrac{5\cdot2^{18}\cdot3^{18}\cdot2^{12}-2\cdot2^{28}\cdot3^{14}\cdot3^4}{5\cdot2^{28}\cdot3^{18}-7\cdot2^{29}\cdot3^{18}}\)
\(=\dfrac{2^{29}\cdot3^{18}\left(5\cdot2-1\right)}{2^{28}\cdot3^{18}\left(5-7\cdot2\right)}=\dfrac{2\cdot9}{-9}=-2\)
