  1. (5 – x)^{3x} : (5 – x)^18 = 1
    => (5 – x)^{3x} = 1 . (5 – x)^18
    => (5 – x)^{3x} = (5 – x)^18
    => 3x = 18 (Cùng bớt đi 5 – x)
    => x = 18 : 3
    => x = 6
    Vậy x = 6

  2. Giải đáp + giải thích các bước giải
    (5 – x)^(3x) : (5 – x)^18 = 1
    (5 – x)^(3x) = 1 . (5 – x)^18
    (5 – x)^(3x) = (5 – x)^18
    => 3x = 18
    x = 18 : 3
    x = 6
    Vậy x=  6
