Answer» Correct option isA3Prime factorising 3087, we get,3087=7×7×7×3×3 =7 3 ×3 2 .We know, a perfect CUBE has multiples of 3 as POWERS of prime factors.Here, number of 7's is 3 and number of 3's is 2.So we need to MULTIPLY another 3 to the factorization to make 3087 a perfect cube.Hence, the smallest number by which 3087 must be multiplied to obtain a perfect cube is 3.verified_topprAnswer VERIFIED by TopprView1485 Views |
