Question

alan
For a= 213 , b = 5/6 and c = 1/2 prove that
a x Cb+c) Cqxb) + (a xC)​

Answer 1

Step-by-step explanation:

() : ×(∩)=(×)∩(×)

∩={1,2,3,4}∩{5,6}=ϕ

∴ .. = ×(∩)=×ϕ=ϕ

×={(1,1),(1,2),(1,3),(1,4),(2,1),(2,2),(2,3),(2,4)}

×={(1,5),(1,6),(2,5),(2,6)}

∴...=(×)∩(×)=ϕ

∴..=..

×(∩)=(×)∩(×)

() : × ×

×={(1,5),(1,6),(2,5),(2,6)}

×={(1,5),(1,6),(1,7),(1,8),(2,5),(2,6),(2,7),(2,8),(3,5),(3,6),(3,7),

(3,8),(4,5),(4,6),(4,7),(4,8)}
