Answer 1

Step:1

The expression is .

   (Evaluate powers: )

  (Multiply: )

            (Add: )

              (Multiply: )

Step:2

                           (Divide: )

                              (Divide: )

                                            (Apply additive inverse property: )

Step:3

Apply subtraction property of equality: Subtract r from each side.

                                            (Apply commutative property: a + b = b + a)

                                                (Apply additive inverse property: )

                                                     (Apply additive identity property: )

                                                          (Subtract: )

Step:4

Apply division property of equality: Divide each side by 2.

                                                          (Cancel common terms)

                                                            (Divide: )

Solution:

The value of expression is .
