Số \(a\) thỏa mãn điều kiện \(a:\left(\dfrac{1}{3}\right)^2=\left(\dfrac{1}{3}\right)^3\) là
\(\dfrac{1}{3}\).\(\left(\dfrac{1}{3}\right)^5\).\(\left(\dfrac{1}{3}\right)^6\).\(\dfrac{1}{18}\).Hướng dẫn giải:\(a:\left(\dfrac{1}{3}\right)^2=\left(\dfrac{1}{3}\right)^3\)
\(a=\left(\dfrac{1}{3}\right)^3.\left(\dfrac{1}{3}\right)^2\)
\(a=\left(\dfrac{1}{3}\right)^5.\)
