The expression x#y denotes the product of the consecutive multiples of 3 between x and y, inclusive. What is the sum of the exponents in the prime factorization of 21#39?
[ "A)17", "B)18", "C)19", "D)20" ]
D
First, let's translate the expression 21#39, using the definition given: 21#39 = 21×24×27×30×33×36×39 We need the prime factorization of this product. Let's factor out 3 from each multiple. 21#39 = 3^7(7×8×9×10×11×12×13) Now let's replace each consecutive integer with its prime factorization: 21#39 = 3^7(7×2^3×3^2×(2×5...
