A.-64

B. 64

C.-5,184

D. 5,184

Hello,

4 * (-2 - (-4)) ^4=4*2^4=4*16=64

Answer B

To answer, directly substitute to the given polynomial the given values of x and y which are - 2 and - 4, respectively.

4 (x - y) ^4 = 4 (-2 - - 4) ^4

= 4 (2) ^4

= 64

Thus, the answer is 64. This is letter B of the choices.
