 Find the smallest number which when multiplied with 3600 will make the product a perfect cube. Further, find the cube root of the product.

Answer»

Here , 3600 = 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5

= 23 × 32 × 52 × 2

Since only one triples is formed and three factors remained ungrouped in triples.

Hence ,the given number 3600 is not a perfect cube.

So  make it a perfect cube we have to multiply it by, 

(2 × 2 × 3 × 5) = 60

3600 × 60 = 216000

Cube root of 216000 is

∛216000 = ∛(60×60×60) 

= ∛(603

= 60

∴ the smallest number which when multiplied with 3600 will make the product a perfect cube is 60 and the cube root of the product is 60.
