use this vector and a mathematical expression to create the following vectors:

vector is x= [1, 2, 3, 4 ,5]

a)x1=[1, 256, 729, 256, 25]

is this correct? x1= x.*[1,128,243,64,5]

Well, there are better solutions. In fact, I'm not sure how much credit your teacher will give you for that. Perhaps if you look a little more closely at your target vector. Do you see anything interesting?

[N/A]

I'm really not sure how else to go about it

[John D'Errico]

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.

Answer 1

[James Tursa]

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
