  • x = -4
    y = 2

    Bagian A
    = (-8x`³)²
    = (-8.-4`³)²
    = (8 . 1/4³)²
    = ( (2³ . 1/(2²)³ )²
    = (2³ . 1/2^6)²
    = ( (2^(3-6) )²
    = (2`³)²
    = 2^-6
    = 1/2^6
    = 1/64

    Bagain B
    = 12(x - y)`²
    = 12(-4 - 2)`²
    = 12(-6)`²
    = 12 . 1/(-6)²
    = 12/6²
    = 12/36 ----- masing² 12
    = ⅓

    Semoga berguna +_+
