giúp mình nhé\(\frac{3^6\cdot45^4-15^{13}\cdot9^{-9}}{27^4\cdot25^3+45^6}\)
\(\frac{3^6.45^4-15^{13}.9^{-9}}{27^4.25^3+45^6}=\frac{3^6.\left(3.3.5\right)^4-\left(3.5\right)^{13}-\left(3^2\right)^{-9}}{\left(3^3\right)^4.\left(5^2\right)^3+\left(3.15\right)^6}=\frac{3^6.3^4.3^4.5^4-3^{13}.5^{13}-3^{-18}}{3^{12}.5^6+3^6.15^6}=\frac{3^{14}.5^4-3^{13}.5^{13}-3^{-18}}{3^{12}.5^6+3^6.\left(3.5\right)^6}=\frac{ }{ }\)
Mình nghĩ hết được rồi
