 Question 175467: Define A@B to be A/B + (A x B). What is the value of 20@(4@2)?Found 2 solutions by jim_thompson5910, Mathtut:Answer by jim_thompson5910(28595)   (Show Source): You can put this solution on YOUR website!First, find 4@2 A@B = A/B + (A x B) ... Start with the given definition 4@2 = 4/2 + (4 x 2) ... Plug in A=4 and B=2 4@2 = 4/2 + (8) ... Multiply 4@2 = 2 + (8) ... Divide 4@2 = 10 ... Add So 20@(4@2) simplifies to 20@10 Now find 20@10 A@B = A/B + (A x B) ... Start with the given definition 20@10 = 20/10 + (20 x 10) ... Plug in A=4 and B=2 20@10 = 20/10 + (200) ... Multiply 20@10 = 2 + (200) ... Divide 20@10 = 202 ... Add So 20@(4@2)=202 Answer by Mathtut(3670)   (Show Source): You can put this solution on YOUR website!20@(4@2) A=20 B=4@2 : (20/(4@2))+20(4@2) : 4@2 A=4 B=2 : (20/((4/2)+(4))(2)+20((4/2)+4(2)) : (20/10)+20(2+8) : 2+200=202
