Question

(-0,4+12/5)[(-2/3+1/2)²

Answer 1

\(=\left(-\dfrac{2}{5}+\dfrac{12}{5}\right)\cdot\left[-\dfrac{4}{6}+\dfrac{3}{6}\right]^2\)

\(=2\cdot\dfrac{1}{36}=\dfrac{1}{18}\)

Answer 2

`(-0,4 + 12/5) . [(-2/3) + 1/2)]^2`

`=(-2/5 + 12/5) . [-4/6 + 3/6]^2`

`=10/5 . (1/4)^4`

`=2.1/36`

`=2/36`

`=1/18`
