Cứu emmmmmmmmmmmmmmmmmmmmm

Giải thích các bước giải:

`a) 14/15 + 4 5/17 + 1 1/15 - 3 5/17`

`= 14/15 + 73/17 + 16/15 - 56/17`

`= ( 14/15 + 16/15 ) + ( 73/17 - 56/17 )`

`= 2 + 1`

`= 3`

`-----`

`b) 27 . ( -1/3)^2 + 1/3 - 25 . ( -1/5)^3 - 1/5`

`= 27 . 1/9 + 1/3 - 25 . (-1/125) - 1/5`

`= 3 + 1/3 + 1/5 - 1/5`

`= 10/3`

`-----`

`c) 2/5 . 5/6 + 1/6 . ( 3/4 - 1/2)^2 . 6`

`= 1/3 + 1/6 . ( 3/4 - 2/4)^2 . 6`

`= 1/3 + 1/6 . (1/4)^2 . 6`

`= 1/3 + 1/6 . 1/16 . 6`

`= 1/3 + 1/16`

`= 19/48`

`-----`

`d) ( 5/2 - 1 )^3 + ( 3/2 - 1/2)^2022`

`= ( 5/2 - 2/2)^3 + 1^2022`

`= (3/2)^3 + 1`

`= 27/8 + 2`

`= 35/8`
