    25
    12
    Option A
    (8^2)^5 ÷ (512/^8)^2 × (8 × 8^2)^3 = (8)^x + 5
    8^10 ÷ (64)^2 × (8^3)^3 = (8)^x + 5
    8^10 ÷ 8^4 × 8^9 = (8)^x + 5
    8^10 – 4 + 9 = 8^x + 5
    8^15 = 8^x + 5
    15 = x + 5
    x = 10

    6070
    3050
    Option C
    x % of (75 × 4 – 150) = 420 + 75^2
    (x/100) * (300 – 150) = 420 + 5625
    (x/100) * 150 = 6045
    3x/2 = 6045
    x = 6045 * (2/3) = 4030
