Question

for any two non empty sets a and b ,a*b is called as

Answer 1

Answer:

===> cartesion product

Step-by-step explanation:

A×B ={(a,b):a€A,b€B}

eg:- two empty sets

A={a1,a2,a3}

B={b1,b2,b3}

CARTESION PRODUCT=A×B=

{(a1,b1)(a1,b2)(a1,b3)(a2,b1)(a2,b2)(a2,b3)(a3,b1)(a3,b2)(a3,b3)}

(a1,b1) which is different from (b1,a1) either

A= pai or B=pai

then A×B = pai

A×B will also a null set
