Step-by-step 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
Answer:
a = 1.44
b = 21.6
c = 3
Step-by-step 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
