Answer

(i) 4 × 528 × 25

⇒ 528 × (4 × 25)

⇒ 528 × 100

⇒ 52800.

Hence, 4 × 528 × 25 = 52800.

(ii) 625 × 239 × 16

⇒ 239 × (625 × 16)

⇒ 239 × 10000

⇒ 2390000.

Hence, 625 × 239 × 16 = 2390000.

(iii) 125 × 40 × 8 × 25

⇒ (125 × 8) × (40 × 25)

⇒ 1000 × 1000

⇒ 1000000.

Hence, 125 × 40 × 8 × 25 = 1000000.
