  1. Đáp án: `= -5/24`

     

    Giải thích các bước giải:

    ` (4/7)^5 . (7/4)^5 – (-1/2)^3 – 4/3`

    `= (4/7 . 7/4)^5 + (1/2)^3 – 4/3`

    `= 1^5 + 1/8 – 4/3`

    `= -5/24`

  2. Đáp án:

     ` (4/7)^5 . ( 7/4)^5 – (-1/2)^3 -4/3`

    ` ( 4/7 . 7/4)^5  +1/ 8  – 4/3`

    ` 1^5 + 1/ 8  – 4/3`

    `=1 + 1/ 8  – 4/3`

    `= 8/8 + 1/8 – 4/3`

    `=  9/8 – 4/3`

    `= -5/24`
