Thank you for the opportunity to help you with your question!

 (x-4)^5

=5C0x^5 - 5C1 x^4*4^!+ 5C2  4^2 x^3  -5C3 4^3  x^2 +5C4  4^4x - 5C5  4^5

=x^5 - 20x^4 +160x^3 -640x^2+1280x-1024


simplified form is 

x^5 - 20x^4 +160x^3 -640x^2+1280x-1024


Please let me know if you need any clarification. I'm always happy to answer your questions.....thank you

(x-4)^5

=5C0 *x^5* 4^0 - 5C1 *x^4*4^1+  5C2  4^2 x^3  - 5C3 4^3  x^2 + 5C4 *4^4 *x - 5C5 *4^5

=x^5 - 20x^4 +160x^3 -640x^2+1280x-1024
