12 is the correct answer

Answer 2

Answer:

1. 11

2. 12

Step-by-step explanation:

In the question

Given a = 2, b = 3

The value of

1. [ab + ba] - 1

where a = 2 , b = 3

= [2 x 3 + 3 x 2] - 1

= [6 + 6] - 1

= 12 - 1

= 11 (Answer)

Now,

2. (aa + bb) - 1

where a = 2, b = 3

= (2 x 2 + 3 x 3) - 1

= (4 + 9) - 1

= 13 - 1

= 12 (Answer)
