thanks.

Determinate A B A = {1.2} and B= {3.2. 1} A = {1. 2} and B = {x| x^3 - 6x^2 + 11x = 6} Show that A is not a subset of B. A = {1.2. 3}|and B = {1.2} A = {1.2. 3} and B = Let X = {1. 2} and Y = {a. b. c}. List the element of each seat. X times Y X times X

Solution

Answer:

To show that A is not subset of B , We have to check if there is any element in set A which is not in B. Here element 3 is not in set B, thus A cannot be subset of B.

A = {1,2,3} , B = PHI

To determine A is not subset of B we have to find if there are elements in A which are not in B , since set B is empty so A can never be subset of B.

X = {1,2} , Y = {a,b,c}

X x Y = { 1a, 1b , 1c , 2a,2b,2c}

Xx X = { 11,12,21,22}
