Question

Multiply 6561 by the smallest number so that product is a perfect cube. Also, find the cube root of that product so obtained.

Answer 1

So,  6561 = 3 × 3 × 3 × 3 × 3 × 3 × 3 × 3

Then to make 6561 a perfect cube. It should be multiplied by 3 and. hence the required cube root is  3 × 3 × 3 = 27

Answer 2

Answer:

6561 = 3×3×3×3×3×3×3×3

grouping grouping of the equal factor in 3's , we see that 3 × 3is left ungrouped in 3's, in order to complete it in triplet, we multiply it by 3

hence, required smallest number→3

and cube root of the product→3×3×3

→ 27
