Question

the smallest number by which 2646 must be multiplied so that product become a perfect cube is​

Answer 1

Answer:

6

Step-by-step explanation:

Prime Factorise 2646.

Its 2×3×3×3×7×7.

3 is paired(since we are asking for perfect cube we need 3 times every number)

2 and 7 are not.

So to make them paired we need to give two more 2's and one more 7.

Hence, 2×2×7=28

2646 should be multiplied by 28.
