Problem 8E

Prove that there are no solutions in integers x and y to the equation x2 – 5y2 = 2. [Hint: Consider this equation modulo 5.]

Step-by-Step Solution:
Step 1 of 3

ACIS 2116 Equations to Know for Exam #1:  Cost of goods sold (retailer) = beginning inventory + purchases – ending inventory  Cost of goods sold (manufacturer): o beginning raw materials inventory + purchases – ending raw materials inventory = amount that goes to WIP o Beginning WIP + requisitioned raw materials (amount that goes to WIP) + direct labor + manufacturing overhead applied – ending WIP = cost of goods manufactured o Cost of goods manufactured + beginning finished goods – ending inventory = cost of goods sold o Cost of goods available for sale = cost of goods manufactured + beginning inventory  Prime costs = direct materials + direct labor
