bạn tách ra
Trả lời :
\(10.\frac{\left(2^2\right)^6+\left(2.3\right)^9\left(2^3.3.5\right)}{\left(2^3\right)^4.3^{12}-\left(2.3\right)^{11}}\)
\(10.\frac{2^{12}+2^{12}.3^{10}.5}{2^{12}.3^{12}-2^{11}.3^{11}}\)
\(10.\frac{2^{12}\left(3^{10}.5+1\right)}{2^{11}.3^{11}\left(2.3-1\right)}\)
\(10.\frac{2.\left(3^{10}.5+1\right)}{3^{11}.5}\)
