whats the answer plz help

Answer:
A,B and D
Step-by-step explanation:
To divide an exponential number we subtract the bottom number's power from the top number's power (the bases should be same)
16^x = 4^2x
[tex] \frac{ {16}^{x} }{ {4}^{x} } = \frac{ {4}^{2x} }{ {4}^{x} } = 4 {}^{2x - x} = 4 {}^{x} [/tex]
you can choose all options that results 4^x.
