Answer:
1) ∛85184 = 44
2) ∛17576 = 26
3) ∛9261 = 21
4) ∛110592 = 48
Step-by-step explanation:
1) 85184 = (2 × 2 × 2) × (2 × 2 × 2) × (11 × 11 × 11)
Take 1 number of group of three
= 2 × 2 × 11
= 44
∛85184 = 44
2) 17576 = (2 × 2 × 2) × (13 × 13 × 13)
Take 1 number of group of three
= 2 × 13
= 26
∛17576 = 26
3) 9261 = (3 × 3 × 3) × (7 × 7 × 7)
Take 1 number of group of three
= 3 × 7
= 21
∛9261 = 21
4) 110592 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2) × (3 × 3 × 3)
= 2 × 2 × 2 × 2 × 3
= 48
∛110592 = 48
