Question

the least number by which 67228 must be multiplied so that product is perfect cube is
a) 16
b) 14
c) 18
d) 88​

Answer 1

Answer:

2 × 2 × 7 × 7 × 7 × 7 × 7 = 67228 . So, to make it as perfect cube, we need triplets. So, we need one 2 and one 7. 2 × 7 = 14. So, it should be multiplied by 14. Hence, option b) is correct answer.
