Answer 1

a = 1.44

b = 21.6

c = 3

Explanation:

a is 1.44 because 1.2 × 1.2 = 1.44

b is 21.6 because 2 × 2 × 2 = 8 so it is 8 + 17 - 3.4 which is 21.6

c is 3 because 9 × 9 = 81 and 3 × 3 × 3 = 27 so 81 ÷ 27 = 3

Answer 2

see explanation

Explanation:

(a)

1.2² = 1.2 × 1.2 = 1.44

(b)

2³ + 17 - 3 × 4 ← evaluate exponent and multiplication before adding/subtracting

= 8 + 17 - 12 = 25 - 12 = 13

(c)

9² ÷ 3³ ← evaluate exponents before dividing

= 81 ÷ 27 = 3
