Answer not giving me an array

y=((x+5)^3)/(x^2) calculate the value of y for the following values of x using element by element operations: 1,2,3,4,5,6.

clc; clear; close all;

%page 86 problem 2

x = [1:6]

y = ((x+5).^3)/(x.^2)

When I get the answer, it's a single number, and I don't think that should be the case.

Kraig - if you want the output to be an array, because you want an element-by-element division of the two rows, you need to prefix the division operator with a period

 y = ((x+5).^3)./(x.^2)

much like what you are already doing for the exponents of 3 and 2.

Without the period, the code is attempting to solve the system of linear equations yA = B, where (in your case) B is the row vector (x+5).^3 and A is the row vector x.^2. See mrdivide for details.

Of course! Thank you!
