#### (1) Compute:

(i) 18 × 30 × 53 × 22

= 1 × 1 × 125 × 4

= 500

(ii) (47)2 × (4-3)4

= 414 × 4-12

= 414-12 = 42 = 16

(iii) (2-9 ÷ 2-11)3

= (2-9+11)3

= (22)3

= 26

= 2 × 2 × 2 × 2 × 2 × 2

= 64

(3) Evaluate:

(i) (-5)0 = 1

(ii) 80 + 40 + 20

= 1 + 1 + 1 = 3

(iii) (8 + 4 + 2)0

= (14)0 = 1

(iv) 4x0

= 4 × 1 = 4

(v) (4x)0 = 1

(vi) [(103)0]5

= [100]5

= 15 = 1

(vii) (7x0)2

= (7 × 1)2

= 7 × 7 = 49
