please help me out with this question

Consider a utility function u(x1, x2) = log(x1 ) + log(x2) Part a. (10 marks) Find the demand function of x1. Part b. (5 marks) Following Part a, derive the mathematical expression for the income-consumption curve that associates with this utility function, fixing p1 = p2 = 1. You do not need to draw the graph. Part c. (5 marks) Following Part a, derive the mathematical expression for the price-consumption curve that associates with this utility function, fixing p2 = 1 =1
