  1. Giải đáp + Lời giải và giải thích chi tiết:
    25 . (-1/5)^3 + 1/5
    = 25 . (-1/125) + 1/5
    = -1/5 +1/5
    = 0
    _____________________________
    \sqrt{(-5)^2} – (2021^0)^2022 – |-1/2|
    = \sqrt{25} – 1^2022 – 1/2
    = 5 – 1 – 1/2
    = 7/2

  2. 25. (-1/5)^3 + 1/5
    = 25. (-1/125) + 1/5
    = -1/5 + 1/5
    = 0
    $\text{ _______________________ }$
    $\sqrt{( -5 )^2}$ – $( 2021^0 )^{2022}$ – |-1/2|
    = 5 – $1^{2022}$ – 1/2
    = 5 – 1 – 1/2
    = 4 – 1/2
    = 3,5
