\(\frac{9^9\cdot225^5\cdot8^7}{18^{12}\cdot625^3\cdot24^3}=\frac{9^9\cdot\left(\left(3\cdot5\right)^2\right)^5\cdot8^7}{\left(9\cdot2\right)^{12}\cdot\left(\left(5^2\right)^2\right)^3\cdot\left(8\cdot3\right)^3}\)
\(=\frac{1}{9^3\cdot2^{12}}\cdot\frac{9^5\cdot5^{10}}{5^{12}}\cdot\frac{8^7}{8^3\cdot3^3}\)
\(=\frac{9^2\cdot8^4}{2^{12}\cdot5^2\cdot3^3}\)
\(=\frac{9\cdot\left(2^4\right)^3}{\left(2^4\right)^3\cdot5^2}\)
\(=\frac{9}{25}\)

1. Tính
a) \(A=\frac{9^{14}.25^5.8^7}{^{18^{12}.625^3.24^3}}\)
Rút gọn: \(A=\frac{9^{14}.25^5.8^7}{18^{12}.625^3.24^3}\)
tính
20112 - ( 304 ++ 2012 ) + ( 2013 + 304)
\(\frac{9^{14}.25^5.8^7}{18^{12}.625^3.24^3}\)
rut gon phan so
914 x 2255 x 87
1812 x 6253 x 243
rut gon phan so a=\(\frac{-8^3\cdot6^4}{18^{12}}\)
A=9^14.25^5.8^7/18^12.(25^2)^3.24^3
