    if x is just being multiplied: 16 If x is an exponent: 621

    Step-by-step explanation:

    I can't tell if the x is an exponent or just being multiplied, so I'm giving you the answer for both

    If x is an exponent:

    5^x - 4 = 5^4 - 4 = 625 - 4 = 621

    if x is just being multiplied:

    5x - 4 = 5 (4) - 4 = 20 - 4 = 16
