\(2^5.9^5.2^8.9^8=\left(2^5.2^8\right).\left(9^5.9^8\right)=2^{13}.9^{13}=\left(2.9\right)^{13}=18^{13}\)
\(2^5.9^5.2^8.9^8=\left(2^5.2^8\right).\left(9^5.9^8\right)=2^{13}.9^{13}=\left(2.9\right)^{13}=18^{13}\)
Tính:
a) \(\dfrac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\)
b) T=\(\dfrac{5^{16}.27^7}{125^5.9^{11}}\)

Rút gọn biểu thức \(\frac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\)
Giúp mình nha mình tích đúng cho
4^5.9^4-2.6^9/2^10.3^8+6^10
\(\dfrac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\)
4\(\frac{1}{2}\)-\(\frac{15}{10.9}-\frac{15}{9.8}-...-\frac{15}{3.2}-\frac{15}{2.1}\)
\(\frac{6}{2.5}+\frac{8}{5.9}+\frac{12}{9.15}\)
\(1-\frac{2}{2.1}-\frac{6}{2.5}-\frac{8}{5.9}-\frac{8}{9.13}\)
Tính: A=\(\dfrac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\)
Rút gọn : A = 4^5.9^4-2.6^9\2^10.3^8+6^8.20
rút gọn P=14^5.9^4-6^9.49^2/2^10.49^3.3^8+6^8.7^5.13
