Um, look at those numbers. Perhaps use factor? You need to make an effort. I won't do it for you. But I am willing to at least push you in a reasonable direction.
So think about the prime factors of the numbers [1, 256, 729, 256, 25]. Tell me what you see.

Yes. It works for me:
>> x= [1, 2, 3, 4 ,5]
x =
1 2 3 4 5
>> x1= x.*[1,128,243,64,5]
x1 =
1 256 729 256 25
