Answer 1

2³ . 16 - 2³ . 14 + 56 =2³.(16-14)+56=2³.2+56=16+56=72

Answer 2

2^3(16-14) +56

= 8.2 +56

= 72

Answer 3

2³.16 - 2³.14 + 56

= 2³.(16 - 14) + 56

= 2³.2 + 56

= 2⁴ + 56

= 16 + 56

= 72

Answer 4

2^3 . 16 - 2^3 . 14 + 56 = 2^3 . 16 - 2^3 . 14 + 2^3 . 7 = 2^3 . (16 - 14 + 7) = 2^3 . 9 = 8 . 9 = 72.

Answer 5

2³x16-2³x14+56=2³x(16-14)+56

                        =8x2+56

                        =16+56

                        =72
