(19)12 × (19)8 ÷ (19)4 = (19)?
সমাধান
সঠিক উত্তর: Option D
(19)12 × (19)8 ÷ (19)4
= (19)12 × (19)8 / (19)4
= (1912 + 8) / (19)4
= 1920/194
= 1920 - 4
= 1916
∴ (19)12 × (19)8 ÷ (19)4 = (19)16
= (19)12 × (19)8 / (19)4
= (1912 + 8) / (19)4
= 1920/194
= 1920 - 4
= 1916
∴ (19)12 × (19)8 ÷ (19)4 = (19)16
