Question

8. Find the smallest number by which 1323 must be
multiplied so that the product is a perfect cube. Also,
find the cube root of the number thus obtained.​

Answer 1

Answer:

In order for 1323 to become a perfect cube, we need to multiply it by 7. This will give us 9261 and the cube root will be 21.

Step-by-step explanation:

Answer 2

1323=3×3×3×7×7

1323=(3×3×3)×7×7× more 7 needed

So,we need more 7 to be multiplied to 1323 to get a perfect cube.

1323×7=9261

9261=3×3×3×7×7×7

9261=(3×3×3)×(7×7×7)

cube root of 9261 =3×7

=21
