When you divide the number 1296 by 6 then it will be a perfect cube. So, the correct answer is “6”.
Is 1188 a perfect cube if not by which smallest natural number should 1188 be divided so that the quotient is a perfect cube also find the cube root of the quotient?We see that 1188 = 2 × 2 × 3 × 3 × 3 × 11 Since 2 & 5 does not occur in triplets, ∴ 1188 is not a perfect cube. To make it a perfect cube, We divide by 2 × 2 × 11 = 44 1188/44= (2 × 2 × 3 × 3 × 3 × 11)/44 27 = 3 × 3 × 3 Since all factor occurs in triplets. ∴ 27 is a perfect cube.
