Answer 2

Answer: 4092

Here's the easiest way to solve this question !

Step-by-step explanation:

62 x 66 = 66 x 62  

              = ( 64 + 2 )( 64 - 2 )

 We will use the identity - ( a+b )( a-b ) =  a²-b²

              ∴ ( 64 + 2 )( 64 - 2 ) = ( 64 x 64 ) - ( 2 x 2 )

                                                       = 4096 - 4

                                                        = 4092

Hope this helps !
