`A=[[1,2] , [3,4]], B=[[5,6] , [7,8]]`,Prove that `Delta(A)dotDelta(B)=Delta(A B)`

A=[[1,23,4]],B=[[5,67,8]], Prove that Delta(A)dot Delta(B)=Delta(AB)

If a Delta b=a-b=5 find (-7)Delta3

If A = {1,2,3,4}, B = {2,4,6,8} then A Delta B =

If A= {1,2,3,4,5,6} and B= {3,4,5,6,7,8,} , then (A-B) uu(B-A) = …………….

If A = {1,2,3,4,5}, B = {0,2,4,6,8} then A Delta B =

If A= {1, 2, 3}, B = (3, 4, 5} then A Delta B = .........

If Delta=|(1,2,3),(2,3,5),(3,6,12)|andDelta'=|(4,8,15),(3,6,12),(2,3,5)| , then a) Delta'=2Delta b) Delta'=-2Delta c) Delta'=Delta d) Delta'=-Delta

If A = { 1 , 2 , 3 , 4 , 5 , 6 , 7 ] And B = { 2 , 3 , 5 , 7 } Then prove that A ∩ B = B

If A = {1,2,4,5} and B={1,4,6} , then A Delta B = ?
