Need help in solving the below,

Find the minimal sum of product expression for the following Switching function. F (x1, x2, x3, x4, x5) = Sm (1, 2, 3, 6, 8, 9, 14, 17, 24, 25, 26, 27, 30, 31) + Sd(4,5)

 

What does your corresponding truth table look like? Perhaps you could post your working thus far.
