a: Sửa đề: 3^2
\(=3^2\cdot\dfrac{1}{3^5}\cdot3^8\cdot\dfrac{1}{3^3}=3^2\)
b: \(=3^{\left(-2\right)\cdot\left(-2\right)}\cdot\dfrac{1}{3^5}\cdot3^3=\dfrac{3^4}{3^2}=3^2\)
c: \(=2^{12}\cdot2^{16}\cdot2^4=2^{32}\)
d: \(=\left[\dfrac{1}{9}\cdot\dfrac{27}{8}\cdot3\right]\cdot\dfrac{128}{81}\)
\(=\dfrac{16}{9}=\left(\dfrac{4}{3}\right)^2\)
