 Hi and welcome to the session. Let us discuss the following question. Question says, find the following square by using the identity. Now before moving on to the solution, first of all recall the identity A plus B whole square is equal to A square plus 2AB plus B square. This identity is true for any value of A and B. This is the key idea behind the given question. Let us now move on to the solution. Now we have to find square of 2 upon 3M plus 3 upon 2N. Now compare this given square with the left hand side of the identity given in key idea. On comparing we get value of A as 2 upon 3M and value of B as 3 upon 2N. Now substituting 2 upon 3 into M for A and 3 upon 2 into N for B on right hand side of the identity given in key idea we get square of 2 upon 3M plus 2 multiplied by 2 upon 3M multiplied by 3 upon 2N plus square of 3 upon 2N. Now applying this law of exponents in this term we get square of 2 upon 3M is equal to 2 upon 3 square multiplied by M square. This plus sign is as it is. Now multiplying constant terms of these three terms we get 2 and variable terms are M and N and their product is M in. Here we write this plus sign as it is. Now again applying this law of exponents in this term we get 3 upon 2N whole square is equal to 3 upon 2 square multiplied by N square. Now we will find out square of 2 upon 3. We know square of 2 upon 3 is equal to 2 upon 3 multiplied by 2 upon 3. Now 2 multiplied by 2 is 4 and 3 multiplied by 3 is 9. So here we write 4 upon 9 for square of 2 upon 3 and this M square is as it is. We will write this term as it is. Now this plus sign is as it is. Now we will find square of 3 upon 2. It is equal to 3 upon 2 multiplied by 3 upon 2. Now 3 multiplied by 3 is 9 and 2 multiplied by 2 is 4. So we get square of 3 upon 2 is equal to 9 upon 4. So here we write 9 upon 4 for square of 3 upon 2 and this N square is as it is. So our required answer is 4 upon 9M square plus 2MN plus 9 upon 4 N square. This completes the session. Hope you understood the solution. Take care and bye for now.
