A=\(\dfrac{12^3\cdot8^3\cdot5}{2^9\cdot\left(3\cdot5\right)^2}\)
A=\(\dfrac{\left(2^2\cdot3\right)^3\cdot\left(2^3\right)^3\cdot5}{2^9\cdot3^2\cdot5^2}\)
A=\(\dfrac{\left(2^2\right)^3\cdot3^3\cdot2^9\cdot5}{2^9\cdot3^2\cdot5^2}\)
A=\(\dfrac{2^6\cdot3^3\cdot2^9\cdot5}{2^9\cdot3^2\cdot5^2}\)
A=\(\dfrac{2^6\cdot3}{5}\)
A=\(\dfrac{64\cdot3}{5}\)
A=\(\dfrac{192}{5}\)
Vậy A=\(\dfrac{192}{5}\)
Tích cho mình nhé!
