A = `[ [ 1 , 7 ] , [ 2 , 5 ] ]` ; B = `[ [ p , q ] , [ a , b ] ]` and A = B , then find the value of a

If A=[[1,7],[2,5]] , B=[[p,q],[a,b]] and A=B then the value of a is

If A=[[1,7],[2,5]] B=[[p,q],[a,b]] and A=B. then the value of a is

If A=[[1,7],[2,5]] , B=[[p,q],[a,b]] and A=B.Then the value of a is

If A=[[4,-1],[5,-3]] and B=[[7,4],[8,-5]] then find the value of A+B and A-B

If A={1,2,3,4,5} and B={1,3,5,7,9} then find the value of (A-B)uu(B-A)

If (3a+2b) : (5a+7b) = 1:2 , then find a : b.

In Fig. 4.177, A C B A P Q . If B C=10 c m , P Q=5c m , B A=6. 5 c m and A P=2. 8 c m find C A and A Q . Also, find the area ( A C B): a r e a ( A P Q) . (FIGURE)

p @ q = p^2 - 20 if p > q , q 2 q = p^2 + 20 if p le q, then for a = 5 and b = 4 the value of [(a @ b) @ (a @ b)] - [(b @ a) @ (b @ a)] is :

if p:q=4:1,p=a+b and q=a-b then find a:b =?
