Using euler or possibly quadratic reciprocity, we can readily decide if an integer a has a quadratic residue modulo a prime p (a) if a has a quadratic residue modulo a prime p and p 3mod 4, show that integer and that a solution to a2 amod p is given by a 4. +1 is an p+1 (b) use part (a) to solve x2 = 7 mod 787.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!
