\(\left(\dfrac{-2}{5}\right)^2\) . \(|\dfrac{1}{3}-\dfrac{3}{5}|\) -\(\dfrac{2}{5}\) \(\sqrt{\dfrac{1}{25}}\) + 1\(\dfrac{1}{3}\)

Tính giúp mik nha, mik đang cần gấp

Answer 1

[Nguyễn Lê Phước Thịnh]

\(\left(-\dfrac{2}{5}\right)^2\cdot\left|\dfrac{1}{3}-\dfrac{3}{5}\right|-\dfrac{2}{5}\cdot\sqrt{\dfrac{1}{25}}+\dfrac{4}{3}\)

\(=\dfrac{4}{25}\cdot\dfrac{4}{15}-\dfrac{2}{5}\cdot\dfrac{1}{5}+\dfrac{4}{3}\)

\(=\dfrac{16}{375}-\dfrac{2}{25}+\dfrac{4}{3}\)

\(=\dfrac{16}{375}-\dfrac{30}{375}+\dfrac{500}{375}\)

\(=\dfrac{486}{375}=\dfrac{162}{125}\)
