Hi,
I need to read in an integer N from the keyboard and then use array processing operation andsummation to compute the value of the expression.
The expression is ((n+1)/sqrt(n)+n^3)

Use the sum() function, if that is allowed.
N = input(.................. % TO DO -- you finish it!
% Get n as a vector [1, 2, 3, 4, ..... N]:
n = 1 : N
Now use your equation ((n+1) ./ sqrt(n) + n .^ 3) , passing it into sum().
Or don't assign n like that, and have a for loop over n and have the equation inside the for loop.

To achieve this you need to read about input and for loop.
  1. Use input and enter the value of N.
  2. Initialize the required sum value to zero.
  3. Run a d for loop from n = 1 to N, inside the loop calculate your formula and sum using the above initliazed value.
