To determine

To compute α1 ,where α=( 1 2 3 4 5 6 2 1 3 5 4 6 )β=( 1 2 3 4 5 6 6 1 2 4 3 5 )

Answer to Problem 1E

  α1=( 1 2 3 4 5 6 2 1 3 5 4 6 )

Explanation of Solution

Given:

  α=( 1 2 3 4 5 6 2 1 3 5 4 6 )β=( 1 2 3 4 5 6 6 1 2 4 3 5 ) .

Concept Used:

  Ifα=( a 1 a 2 a 3 b 1 b 2 b 3 )thenα1=( b 1 b 2 b 3 a 1 a 2 a 3 )

Calculation:

Use the above concept to find α1 .

  α=( 1 2 3 4 5 6 2 1 3 5 4 6 )α1=( 1 2 3 4 5 6 2 1 3 5 4 6 ) .

Conclusion:

Thus, α1=( 1 2 3 4 5 6 2 1 3 5 4 6 )

To compute αβ ,where α=( 1 2 3 4 5 6 2 1 3 5 4 6 )β=( 1 2 3 4 5 6 6 1 2 4 3 5 )

Answer to Problem 1E

  βα=( 1 2 3 4 5 6 1 6 2 3 4 5 ) .

Explanation of Solution

Given:

  α=( 1 2 3 4 5 6 2 1 3 5 4 6 )β=( 1 2 3 4 5 6 6 1 2 4 3 5 )

Concept Used:

  Ifα=( a 1 a 2 a 3 b 1 b 2 b 3 )andβ=( b 1 b 2 b 3 a 1 a 2 a 3 )thenαβ=( a 1 a 2 a 3 a 1 a 2 a 3 )

Calculation:

  βα=( 1 2 3 4 5 6 6 1 2 4 3 5 )( 1 2 3 4 5 6 2 1 3 5 4 6 )βα=( 1 2 3 4 5 6 1 6 2 3 4 5 )

Conclusion:

Thus, βα=( 1 2 3 4 5 6 1 6 2 3 4 5 )

Answer to Problem 1E

  αβ=( 1 2 3 4 5 6 6 2 1 5 3 4 )

Explanation of Solution

Given:

  α=( 1 2 3 4 5 6 2 1 3 5 4 6 )β=( 1 2 3 4 5 6 6 1 2 4 3 5 )

Concept Used:

  Ifα=( a 1 a 2 a 3 b 1 b 2 b 3 )andβ=( b 1 b 2 b 3 a 1 a 2 a 3 )thenαβ=( a 1 a 2 a 3 a 1 a 2 a 3 )

Calculation:

  αβ=( 1 2 3 4 5 6 2 1 3 5 4 6 )( 1 2 3 4 5 6 6 1 2 4 3 5 )=( 1 2 3 4 5 6 6 2 1 5 3 4 )

Conclusion:

Thus, αβ=( 1 2 3 4 5 6 6 2 1 5 3 4 )
