Question

what is the smallest number by which 3087must be multiplied so that the product is perfect cube?​

Answer 1

Answer:

3087 must be multiplied by 3. Please mark me brainliest.

Step-by-step explanation:

First we need prime factorisation of 3087

3  3087

3  1029

7  343

7  49

7  7

   1

So, 3087 = 3 x 3   x    7 x 7 x 7

3087 = $3^2$ x $7^3$

3087 x 3 = $3^2$ x 3 x $7^3$

3087 x 3 = $3^3$ x $7^3$ =(3 x 7 $)^3$ = 21^3
