Question

Find the smallest number by which when multiplied by 1800 will make a perfect cube

Answer 1

Answer:

15

Step-by-step explanation:

If we do prime factorization we get 2*2*2*3*3*5*5.

So it must be multiplied by 3 and 5 to make it a cube.

3*5=15

Answer 2

Step-by-step explanation:

1800=225* 2 cube

= 3square* 5square*2cube

so 225 is the only non trivial answer. on divivding 225 we get 8.

so 8 is a perfect cube of 2.
