Question

Find the smallest number which when multiplied with 4000 will make the products perfect cube. Also find the cube root of the product

Answer 1

Answer:

2

20

Step-by-step explanation:

Find the smallest number which when multiplied with 4000 will make the products perfect cube. Also find the cube root of the product

4000 = 2 * 2 *  2  *  2  *  2  *  5 * 5 * 5

4000 = 2³ * 2² *  5³

To make it perfect cube we need to multiply it by 2

4000 * 2 = 2³ * 2² *  5³ * 2

=> 8000 = 2³ * 2³ *  5³

=> 8000 = ( 2 * 2 * 5)³

=> 8000 = (20)³

=> ∛8000 = 20

the smallest number which when multiplied with 4000 will make the products perfect cube = 2

cube root of the product = 20
