What is 5×-4 simplify each expression for x=4

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
