Question

Answer 1

a: \(=\left(\dfrac{5}{2}\cdot\dfrac{4}{5}\right)^3=2^3=8\)

b: \(=\left(\dfrac{1}{3}\right)^4:\left(\dfrac{1}{3}\right)^3=\dfrac{1}{3}\)

c: \(=\left(\dfrac{9}{5}:\dfrac{-27}{20}\right)^3=\left(\dfrac{9}{5}\cdot\dfrac{-20}{27}\right)^3=\left(-\dfrac{4}{3}\right)^3=-\dfrac{64}{27}\)

d: \(=3^3\cdot3^8=3^{11}\)
