First we find out the prime factors of 210125,

210125 = 5 × 5 × 5 × 41 × 41

∵ one triples remained incomplete, hence 210125 is not a perfect cube.

We see that if we multiply the factors by 41, we will get 2 triples as 2³ and 41³.

And the product become:

210125 × 41 = 8615125 = 5 × 5 × 5 × 41 × 41 × 41

Cube root of product =
