Solutions:

1. After solving this we find value = 288
:. โ(?) = โ(288)2 = โ(82944)

3. ? = (21% of 1326) โ (17% of 932)
= [(21 ร 1326) / 100] โ [(17 ร 932) / 100]
= 278.46 โ 158.44
= 120.02
Alternate Method:
? = (21% of 1326) โ (17% of 932)
= 21% of 17 ร 78 โ 17% of 932
= 17% of (21 ร 78 โ 932)
= 175 of (1638 โ 932)
= 17% of 706
= 120.02

4. ? = โ(182.25) = โ(18225 / 100) = (135 / 10) = 13.5

5. ? = โ(1331)1/3 โ (343)1/3
โ[{(11)3}1/3 โ {(7)3}1/3]
= โ(11 โ 7) = โ4 = 2

6. ? = (28512 / (264 ร 6)) = 18

7. ? = [(x ร x ร x ร x) / (y ร y ร y ร y)] = [x4 / (4 ร 5)] = [(4)2 / (4 ร 5)] = (256 / 20) = 12.8

8. [1024 ร (18 / 100)] + [? ร (26 / 100)] = 486.96
=> [(18432 + 26 ร ?) / 100] = 486.96
=> 26 ร ? = 48696 โ 18432 = 30264
:. ? = (30264 / 26) = 1164

9. ? = 24 ร [(9 / 25) ร (16 / 64) ร (25 / 36)] = 24 ร (1 / 16) = 1.5
