Write a MATLAB script that asks the user to input the values for three variables $a,b,$ and $c,$ and computes the

value of $x$ where:

$x=\frac{\sqrt[\phantom{2}]{a-b+2a^2}}{c}$

The script should take care of the problem of dividing by zero or getting a negative number under the square

root. The script should print the appropriate messages accordingly $($i$.$e$.$ "DIVIDING BY ZERO", or$,$ "NEGATIVE

NUMBER UNDER SQUARE ROOT"$).$ If both errors occur, the script should print both messages. If no error

occurs, the script should print the value of $x.(40$ pts$)$

Write a MATLAB script to calculate the following summation $(40$ pts$)$:

$x={\displaystyle \underset{k=1}{\overset{200}{}}}[(-1{)}^k\frac{5k}{k+1}]$
