thực hiện phép tính ạ

Đáp án:

 `(1\frac{1}{5}-1\frac{1}{3})^{2}:|\frac{-2}{225}|-(\frac{1}{2}.\frac{1}{3})^{3}.\sqrt{1296}`

`=(\frac{6}{5}-\frac{4}{3})^{2}:\frac{2}{225}-(\frac{1}{6})^{3}.36`

`=(\frac{18}{15}-\frac{20}{15})^{2}.\frac{225}{2}-\frac{1}{216}.36`

`=(\frac{-2}{15})^{2}.\frac{225}{2}-\frac{36}{36.6}`

`=\frac{4}{225}.\frac{225}{2}-\frac{1}{6}`

`=\frac{2.2.225}{225.2}-\frac{1}{6}`

`=2-\frac{1}{6}`

`=\frac{12}{6}-\frac{1}{6}`

`=\frac{11}{6}`
