Answer 1

\(\left(\dfrac{-1}{3}\right)^2-\left[\left(-\dfrac{5}{2}\right)-\left(1,5-\dfrac{8}{3}\right)\right]=\dfrac{1}{9}-\left[\left(\dfrac{-5}{2}\right)-\left(\dfrac{-7}{6}\right)\right]=\dfrac{1}{9}-\left(\dfrac{-4}{3}\right)=\dfrac{13}{9}\)

Answer 2

(-1/3)² - [(-5/2) - (1,5 - 8/3)]

= 1/9 - (-5/2 + 7/6)

= 1/9 + 4/3

= 13/9

Answer 3

`@` `\text {Ans}`

`\downarrow`

`d)`

`(-1/3)^2 - [(-5/2) - (1,5 - 8/3)]`

`= 1/9 - [(-5/2) - (-7/6)]`

`= 1/9 - (-4/3)`

`= 13/9`
