Answer:

A. -2 + 12 -2 ^ 3 + 2 ^ 0 * 3

= 10 - 2 ^ 3 + 2 ^ 0 * 3

= 10 - 8 + 1

= 3

B. 9 ^ (1/2)(25) - 8 + 2 + 3 ^ 2

= 9 ^ (1/2)(25) - 6 + 9

= 3 ^ 25 + 3

= 3 ^ 25 + 3

= 847288609446

C. 1/2 * 3/5 * (2 ^ 3 - 6) + 1/5

= 1/2 * 3/5 * 2 + 1/5

= 3/5 + 1/5

= 4/5

  • See below

Step-by-step explanation:

A.

  • - 2 + 12 - 2 ^ 3 + 2 ^ 0 * 3 =                  Exponent
  • -2 + 12 - 8 + 1*3 =                                  Multiplication
  • -2 + 12 - 8 + 3 =                                     Addition and subtraction
  • 5

B.

  • (9) ^ (1/2) (25) - 8 + 2 + 3 ^ 2 =              Exponent
  • (3)(25) - 8 + 2 + 9 =                               Multiplication
  • 75 - 8 + 2 + 9 =                                      Addition and subtraction
  • 78

C.

  • 1/2 * 3/5 * (2 ^ 3 - 6) + 1/5 =                    Exponent within parenthesis
  • 1/2 * 3/5 * (8 - 6) + 1/5 =                          Parenthesis
  • 1/2 * 3/5 * 2 + 1/5 =                                 Multiplication
  • 3/5 + 1/5 =                                               Addition
  • 4/5
