Compute the value of the Jacobi symbol (8/21) by breaking it into the product of Legendre symbols. Explain your thought process and show your work. What does the result tell us about whether or not 8 is a quadratic residue mod 21? Next calculate 8^21-1/2(mod 21). You may use any code you have written. What does your result tell you about whether or not 8 is a quadratic residue mod 21? Finally, compare the values you got for the two different computations, and comment on whether they are the same/different and what that means

Question 61 1 pts 61. You generate a hypothetical mutant mouse in which dendritic cells or macrophages cannot interact with CTL. You infect this mouse with LCMV and follow the infection over time. You compare this to a control experiment in which you infected a normal (unaltered) mouse with LCMV. Based on what was covered in the course, what do you expect to observe? (A) The mouse will live without pathology (B) The mouse develops strong pathology (C) The number of CTL will be higher in the mutant compared to the normal mouse (D) B and C (E) Non-lytic immune responses will fail, resulting in a larger number of CTL
