Question

Answer 1

`a, (-5/4)^2 : (-35/24)^2`

`= (5/4)^2 : (35/24)^2`

`= (5/4 : 35/24)^2`

`=(6/7)^2`

`= 36/49`

`b, (-1/2)^2 . (2/5)^2`

`= (-1/2 . 2/5)^2`

`= (-1/5)^2`

`= 1/25`

Answer 2

`c, (1/9)^2 : (1/3)^3`

`= 1/81 : 1/27`

`=1/81 . 27`

`=27/81`

`=1/3`

`d,(-1/2)^3 . (3/2)^3`

`= (-1/2 . 3/2)^3`

`= (-3/4)^3`

`= -27/64`
