Hello. Please explain and fully solve the problem. Appreciate the help!

1. Use any one of Ln Rn, Mn, Th, or S, to find a numerical approximation of J V1 + x3dx that is accurate to three decimal places and uses the smallest possible n. Use Calculus to explain how you know the n you have chosen is the smallest possible. Feel free to use a calculator but clearly indicate the evaluation points. hint: n will depend on which approximation you choose to use
